Silent laughter

As I watch my Son dealing with situations with his children I usually end up laughing. I begin realizing that I am watching the Circle of Life. I can laugh now but I sure wasn't laughing when my children were young and doing the same kind of things. My son was the one that wasn't laughing now. In some situations he welcomes ny words of wisdom as I pass on what I have learned. Other times if I begin to utter a word I see by the look on his face that it is wise if I just walk away and laugh silently inside.
