I'm loving the answers! Thanks for posting.
I answered upthread I don't come from a huggy-kissy family. But as someone else posted upthread, NYC (where I live) is a place where friends and acquaintances often kiss as a greeting; as a result I have become more kissy then I learned int eh home.
But its interesting to read the answers because honestly in the last year or so one of DH's friend's acquired a new girlfriend/now wife. She and I see each other often and while not close, are certainly friends. She is a lip kisser. It always freaked me out a tad. She's I think toned it down a bit and I've learned to turn my head more, and ultimately it doesn't bother me that much, so its all good, but I'd thought it was weird. Its interesting to read that for many people, its just commonplace.
