not all families are the touchy feely kind.
you are right stoppit.
Initially my inlaws thought that it so odd that us siblings and cousins are always hugging each other. To them - you hug to console each other.
My younger brother was over this weekend and he always drapes his hands over my shoulder.
At one point my husband kiddling said to him "let go of my wife dude"
He said "dude - she was my sister first"
