For example, I am way more outgoing with a certain group of friends, and while I wasn't as much with another group of friends, I trained myself to be, and that has greatly helped me, and so, when they introduce me to friends or whatever, I'm at the top of my game.

However, I ran into a girl two days ago who I used to be friends with, and she was super outgoing and extroverted. I devolved into the shy and awkward version of myself and I noticed that this sometimes happens to me. Does this happen to anyone else, and how do you work on that?
