Today I was told by two women in a group. That I am "expressionless" in general and "having a poker face" because I didnt smile wide in a selfie. What I've been doing in general is smirking a lot instead of smiling etc, typical advice.

They asked me to smile for them, I kept smirking and they seemed a bit frustrated. Wtf?

Body language and general vibe was good though. Am I reading too much into this?
