I hug my husband and one of my daughter in laws.
Neither my other daughter in law* nor my 2 sons* are huggers.
My in-laws are huggers, and I don't like hugging them, so on the rare instances we are in same room together I will avoid that by keeping busy and just saying 'hi' from across the room.
I didn't grow up in a hugging family, but now that my folks are older we hug each other when we see one another periodically throughout the year, but that only started when they moved farther away.
*obviously, things like when they got married or graduated I hugged them!
