I don't see my dad often but when I do we always hug hello and goodbye. I hug my sisters and mom all the time. I think nearly all of us don't get enough hugs; I have a boxing bag and one time broke down and sort of wrapped my arms around it crying. The physical act softens our heart. The day to day of modern life hardens our heart. I think Jesus would give us a big hug if he could. One thing I look forward to most about having a wife is being able to get hugs all the time.
