Well when I am in private with my friends, I am generally myself. However, when someone asks for my picture, or I am walking around the convention grounds, I try to be as "in character" as possible when I am cosplaying. I would say that it's 75%/25% split for me, 75% being the time I try to be in character. I have to admit though, it doesn't really bother me when cosplayers are "out of character" when they're cosplaying. I mostly like to see their costumes, and admire the work they've put into it.
Same here. I try to be in character but when I'm with friends that doesn't happen unless they are doing a group cosplay with me.
