I was not raised in an affectionate household. I did raise my children with a lot of hugs and kisses. My husband and I have always displayed respectful affection in front of our children. I usually hug people that I care for when I greet them and say goodbye. I do have some people who are not comfortable with displays of physical affection. So, I only hug them when the situation calls for it. So, it depends on the person and the situation.
Because I believe life is short, I always make sure people in my life know they are loved, if not by a hug than at the very least with my words.
