My maturity level is basically a mirror.

Depending on who I'm around, I can be very mature and calm or immature and playful. I mirror whoever I'm around and change my behavior accordingly to make the people around me feel more comfortable.

I like goofing off with playful people, but I also greatly enjoy having mature conversations with calm people. I've been told that I have a very "animated" personality, and I think that comes out of me more when I'm comfortable with the people around me.
