We've established that kissing someone on the cheek or both cheeks in greeting or farewell is very much a European thing, but what about a hug hello/goodbye?
I am a hugger but mostly with my parents and sister.
I don't even hug my best friend because I know she's not a hugger (although we have hugged when one of us is very upset).
I don't hug people I'm not close to but if someone hugs me I will hug back even if it feel awkward.
You can literally see me cringe anytime I'm confronted by a hugger who jumps in for a hug. I will respond as best as possible to not make it any more socially awkward but in general, I'm very limited in who is OK touching me. Like I don't even like mani pedis or massages because having a stranger put their hands on me makes me stiffen up.
