What is the typical way you act out of character? I mean, a trait you frequently fall back on but is mostly incongruous with who you are?
Me: I frequently act bright and cheerful around other people, not because I am cheerful but because I become cheerful in response to stress (including the presence of other human beings). It's not insincere, I genuinely feel cheerful, but the feeling has got nothing to do with my inner state.
Over to you.
(It would be nice if this could be related to Socionics, hence it's in "General Discussion" and not "Anything Goes", but in light of recent topics please avoid saying "I frequently act XXXx" because that's not what I'm looking for).
