I'm glad you heard from your son. I'm sure it must be nice to hear how he is doing. My brother went through Marine bootcamp many years ago. One story that still makes me laugh is that he went through Marine boot camp at the same time that I went through Air Force boot camp. After we were done, we both came home to visit our parents at the same time. He was unpacking his duffel bag and pulled out these ratty old combat boots with absolutely no tread left on them. So I said to him "gee the Marines don't have enough money to give you new combat boots when you join up" and he said what are you talking about - these were new when I got them. After six weeks of what I thought was intense basic training in the Air Force, my combat boots till looked relatively new. It was then that I realized how happy I was I joined the Air Force instead of the Marines:-)!
I hope you have a nice evening with your sister. I think it is good that you are getting out and taking care of you. Have a great weekend!
