Aiden only glanced over when the man spoke up about over-working. Well, he wasn't wrong about that. Though, most of the time, they weren't the ones that got to decide how they spent their time. Their superiors were the ones that scheduled their work. In his case, he worked the optional over-time as something to do and then it was his own choice to go be a hero outside of work. That wasn't really something he was about to bring up, he was just planning to keep to himself. He didn't want to talk right now, with being tired and not knowing what to say most of the time. He wasn't really comfortable talking to people he didn't know, usually in fear that new people would just hate him immediately. He was too tired to worry about that kind of stuff, so he just decided not to respond to that comment.
Even though, Aiden hadn't responded to the first comment, the doctor decided to continue with speaking. The doctor suggested he get a cup of coffee. Aiden shrugged, "I don't like coffee. If the fresh air doesn't wake me up enough, I'll just take the bus or walk home. And warm drinks don't actually warm you up, it actually causes your body to think that you're too hot causing your body to try and cool itself down. The same thing with cold drinks, they don't cool you they cause your blood vessels to tighten and will warm your body up." He woke up a bit when he actually started talking about the drinks causing different effects than what most people think. He even perked up a bit, and looked over at the other man with a smile, but then he realized how that probably sounded really pretentious. He didn't really mean to sound that way, he just knew that interesting fact and he liked sharing those sort of things. He sighed, the smile quickly faded and his eyes shfted back over to the numbers. "And you probably didn't need to know that, or cared about that information. Sorry, it just slipped out, I'm tired."
