Have 你 ever felt that in a way your like kaoru in real life?

because I have a friend like hikaru and when I'm around her I act almost as bad (not like drugs 或者 anything like that, 更多 like hyper and mischievousness :O ) as she does, but I recently noticed that when she's not around I'm actually 更多 calm, collected, accepting and 更多 like the typical me. not the Otaku (forgive me other otakus bueacuse both I and my friend are otaku) hyper me.

is that not odd?

but what about you?
