my dad's side of the family hugs everyone. when you leave you receive a hug from everyone. My mom sort of adopted a post doc and brought her a long to KY and they had only met her 3 days before and everyone hugged her. I don't know if it's a central KY thing or what. as a contrast my room mates family in New England never hugged me, and I don't expect them to either. so I'm wonder if this is a culture thing or just something my family does.
