I know it’s not just me, but why do our mouths contort into weird shapes when we rub our eyes?
That’s all. 
Since this is MPSIMS and not FQ, I’ll bite! I just tried it out, and I think I do it in order to stretch the skin around my eyes a bit so it doesn’t wiggle around with my finger.
Yep. Same reason most women open their mouths while putting on eye liner or such.
My mouth doesn’t move, but my eyebrows are trying to jump off my face and run down the street.
It may not be just you, but it definitely doesn’t include me.
