Is it normal to use lines from video games?
I've noticed I quite often talk to myself (in my head, not out loud) using lines from video games.
For example, if I'm gonna make coffee I may say "I think I need a good cup'a java" (Heavy Rain), or when I'm confused I say "What... the hell?" in Henry's voice (Silent Hill 4).
Am I the only one doing this? Is it normal?
