Here's my breakdown.
Family - hug
Friends - side hug
Coworker - usually zero physical contact...at most a handshake if required
Acquaintance - handshake
Friend of a friend - handshake
Stranger - no physical contact
10-15 years ago...it would've been hugs for everyone...now I'm just trying to stay out of trouble
