Instead of having an alter ego, I feel that I am more a mix of two people at the same time, shifting to one side or the other slightly on occasions. Most of the time I am both somewhat serious and fun-loving at the same time, but depending on the situation, I can switch into one of my personalities more noticeably. For example, when I am in a slightly uncomfortable situation, I act more serious and only talk when I feel like it is needed, like Batman. But when I grow more comfortable or am not thinking about work at all, I am like the Joker in which I can't stop talking and I'm trying to make jokes. Except I'm not a crazy murdering sociopath trying to kill everyone. Or at least not yet anyway.
