I find that if my family and I are serious too often we tend to all become quite distant from each other. I am not saying that we should only have fun everyday, everyone needs to have some seriousness in their life. What I am trying to say is to be truly happy in life one must make time for fun.
Hardly any money needs to spent, you don’t even need to leave the house. A good example was a little spontaneous fun we had last night. My teen daughter found a long cardboard tube, those ones used for rolls of wrapping paper, and she made noises and danced around living room! She made both me and her little sister laugh hysterically. This went on for about a half an hour. We laughed until tears streamed down our faces. Laughter truly is the best medicine, I felt so much better after that. So grab an empty roll of wrapping paper and have a little fun with it.
