"Help!" I shouted as I seen a boy run past me. He stopped and looked back then helped me up.

"Are you okay?" he asked looking back over his shoulder. It's only been 3 days since the apocalypse started. I was on my own and I knew I would have to trust to get through this.

"I mean I've been better but yeah." I said trying to make him laugh. It didn't work, but I needed to be able to trust him so we could work together to get through this. I wasn't paying attention and he grabbed my hand and pulled me behind a building as robots went past.

"You know we might as well stay together because that's two times I've saved you" he said as he locked eyes with me. I felt my cheeks get warm but I ignored it.

"I mean it would probably be safer to stay together." I said looking at him. He smiled and we headed off trying to stay hidden.
