Just after Mike sat down in the train, another boy entered it, causing him to look up. So apperently he wasn't even the last one to arrive, which kind of surprised him. He was usually always the last, but never let it bother him. He figured this time he'd make no big deal out of it, neither, especially not since the boy seemed nervous enough about it already. So instead, he simply sat back in his seat and looked around at the other people for a moment. 

Luckily enough, the vehicle came to a halt before he could get bored of doing so. He got out of his seat and got up, his left leg making a soft,  barely audible, mechanic noise as he got up. It as no big deal, but he would have to fix that later. Looking at the guy who's had got into the train last, Mike got over to him and smiled friendly.  "Hey, I just noticed you getting in and figured I'd say hi. My name is Mike." He said with a friendly smile.
