yes, 100%. It's not something I consciously do, I just do. not even like acting differently around your best friend, a distant family member and someone you've just met, because I think almost everyone does that.
When I'm speaking to someone (online) I'll change my whole typing style to match or almost match theirs, I don't want to say I "copy" people because I don't really feel like that's what I do but I often become interested in things that the person I'm speaking to in interested in even if it's not at all something I'd be into. basically I don't have a personality and i don't know who i am so it's completely molded by who I spend time with and what I see
