The best way to predict the future is to create it.
I have two sons, Slade and Seth. Seth is my youngest (age 28). Slade is 30. Seth made parenting easy. Slade on the other hand caused us some angst during the process (I hope this public statement doesn't shock him).
About a month ago Seth called and asked, "Do you want the good news or the bad?" I answered, "The Bad." He laughed and said, "I have a tattoo." Seth isn't in the Navy so this revelation shocked me. After a moment he explained that he had, "Who dat?, a Fleur de Lis, and Superbowl XLIV Champions" tattooed on his upper arm.
