No, my family were not big on hugging. But, my first wife's (and the mother of my children) family were. We made sure to raise our children with a lot of physical contact.
I remember when my son was about 6, we were leaving my parents house, and my son went to kiss and hug my father. My father stopped him and told him he was to old
for that and instead shook hands with him. I still remember the look on my son's face, confusion, loss. I still kiss my son and daughter on the cheek when ever I see them.
( they are both in their mid 30's) I think this has kept us closer than I was with my father after growing up. Please don't misunderstand, I think I came from a good upbringing.
It's that I think that acting differently as you grow older, a closeness can be lost in the relationship.
I find it interesting also that as we have gotten older and had children of our own, my brothers have grown to become huggers again.
