The Hardest Part

I love coming out here to visit my daughter and her family or going to see my son and his family. But then I have to leave and go home. That is the hardest part. I wish I did not have to leave but I wish they did not live so far away. But I can't tell them where to live. I try to drop suttle hints but it does not work they are grown now and have families of their own. I would baby sit when ever for free! They could go on dates with their husband/wife. But it doesn't work. They are grown and not coming back home now. So I am sad. What am I supposed to do now? My heart hurts and I want to cry; I probably will tomorrow when I have to leave for the plane. It hurts more and more every time. Will it ever get better?
