This is a bit Andy-Rooneyish…
I only kiss my wife and my daughter on the lips at this point, although I used to kiss all female family members and other close female friends in this way, before I was married. Now with F family members, its usually a “just-off-the lips” kiss (not a cheek or fake cheek kiss).
Most of my wife’s friends I’m introduced to I’ll shake hands with (not a cold fish, but not overly-firm either- and bases of thumbs don’t touch), and as I get to know them, I’ll cheek-kiss. I don’t make it a habit everytime I see them; just if it seems comfortable/appropriate. Sometimes a hug is more apropos one reason or another.
Almost all guys get handshakes - firmer but not vise-grip like unless I get that on the other end. Old friends can get hugs on final goodbyes after reunions. Certain guys who do it often I will match with the handshake/bro-shake/slap on the back hug, but it’s not my thing to initiate.
A three step soul handshake can often make me feel real WHITE, but I can pull it off once if the other guy isn’t trying too hard to out-brotha me.
Younger daughters of couples we’re closer friends with can seem awkward at goodbye times - a hug works sometimes to overcome this, but isn’t always natural. Teen & pre-teen boys receive handshakes/high-fives. I’ll even resort to a wave or group-wave goodbye to the kiddies if I don’t get a warm vibe.
