But that wasn’t all. People had sent money. Actual money. Someone had opened an online donation account to help with the vet’s fees because they wanted Norman to be okay and left a message telling him how he could access it using a PayPal account.

I can’t donate enough to put your sister through school, but I can put something towards a new puppy for your sister if your dog doesn’t make it. I’m glad she has you.

Hey Gothboy (is that your real name??) have you thought of a rescue dog? That way something good might come out of it. I enclose a contribution! Rescue centres always need donations ;-)

A little something to help with the vet’s bills. Give your sister a hug from me. I’m so mad at what happened to you all.

My dog got hit by a car and was saved by the PDSA. I’m guessing you don’t have one near you. I thought it would be nice, as someone helped me, to help you a little. Please accept my £10 towards his recuperation.

From a fellow girl maths geek. Please tell your little sister to keep on. Don’t let them win.

It had gone viral. There were 459 shares. Nicky counted a hundred and thirty names on the donations page, two pounds being the smallest donation, and two hundred and fifty the highest. A total stranger had sent two hundred and fifty pounds. The final tally sat at £932.50, the last having come in an hour previously. He kept refreshing the page and staring at the figure, wondering if they had put a full stop in the wrong place.

His heart was doing something really strange. He placed his palm against his chest, wondering if this was what it felt like to have a heart attack. He wondered if he was going to die. What he wanted to do, though, he discovered, was laugh. He wanted to laugh at the magnificence of total strangers. At their kindness and their goodness and the fact that there were actual people out there being good and nice and giving money to people they had never met and never would. And because, most crazy of all, all that kindness, all that magnificence, was sitting there just because of his words.

Jess was standing by the cupboard holding a parcel of pink tissue when he scooted into the living room. ‘Here,’ he said. ‘Look.’ He pulled at her arm, dragging her over to the sofa.

‘What?’

‘Put that down.’

Nicky opened the laptop and placed it on her lap. She almost flinched, as if it was actually painful for her to be so close to something that belonged to Mr Nicholls.

‘Look.’ He pointed at the donations page. ‘Look at this. People have sent money. For Norman.’

‘What do you mean?’

‘Just look, Jess.’

She squinted at the screen, moving the page up and down as she read, then reread it. ‘But … we can’t take that.’

‘It’s not for us. It’s for Tanzie. And Norman.’

‘I don’t understand. Why would people we don’t know send us money?’

‘Because they’re upset about what happened. Because they can see it wasn’t fair. Because they want to help. I don’t know.’

‘But how did they know?’

‘I wrote a blog about it.’

‘You did what?’

‘Something Mr Nicholls told me. About finding your people. I just … put it out there. What was happening to us.’

‘Show me.’

Nicky switched pages then and showed her the blog. She read it slowly, her brow furrowed in concentration, and he felt a bit strange, like he was showing her part of himself that he didn’t show anyone. Somehow it was harder to show all that emotional stuff to someone you knew.

‘So, how much is the vet?’ he said, when he could see that she’d finished.

She spoke like someone in a daze. ‘Eight hundred and seventy-eight pounds. And forty-two pence. So far.’

Nicky lifted his hands in the air. ‘So we’re okay, yes? Look at the total. We’re okay!’

She looked at him and he could see on her face the exact expression he must have worn half an hour previously.

‘The kindness of strangers,’ he said.

She lifted her hand to her mouth. ‘I just can’t believe that people would send money to someone they don’t even know.’

‘It’s like you said. Good things do happen.’ Nicky wanted her to smile. He wanted her to feel like he did, like a door had opened onto a world he hadn’t even known about, full of kind people and the possibility of happiness.

‘It’s good news, Jess! Be pleased!’ And for a minute her eyes brimmed with tears. And then she looked so confused that he leant forward and hugged her. This was his third voluntary hug in three years.

‘Mascara,’ she said, when she pulled back.

‘Oh.’ He wiped under his eyes. She wiped hers.

‘Good?’

‘Fine. Me?’

She leant forward and ran a thumb under the outer edge of his eye.

Then she let out a breath and suddenly she was a bit like the old Jess again. She stood up and brushed down her jeans. ‘We’ll have to pay them all back, of course.’

‘Most of them are, like, three pounds. Good luck with working that out.’

‘Tanzie will sort it.’ Jess picked up the pink tissue parcel, and then, almost as an afterthought, she shoved it into a cupboard. She pushed her hair from her face. ‘And you have to show her the messages about maths. It’s really important she sees those.’

Nicky looked upstairs towards Tanzie’s bedroom. ‘I will,’ he said, and just for a minute his mood dipped. ‘But I’m not sure it’s going to make any difference.’
