The ususal story here. Non-hugging family. Hugging is now one of my standard options for greeting people.

I have tended to think of hugging as a "boomer" thing. I don't remember my parents and their peers doing much of it. I remember hugging more as something adults did with children.

I usually hug only people I know. It is not my default greeting for first contact. But I don't hug everybody I know. Some people come across as more standoffish than others.

The only realy dilemma I sometimes face is when to start hugging in the relationship. I try to err on the side of hugging.
