Most of us don't live in the same state as our children. I think it's safe to say that at least one of your children doesn't live very near to you. So do you go see him? Probably not as much as you'd like to because you're tied down.
I was talking to friend of mine and he was gone for a couple weeks. When he came home, he said it was horrible.
He had to mow the lawn.
He had to wash off things.
He had to clean the windows.
He had the vacuum the house.
All the things that didn't get done when he was gone. Why come back to that? Why not be able to go away for a couple weeks to go visit your grandchildren that love you. Have a good time! Go on a trip to Europe, or go back to college. Go do whatever you want to do, but don't be tied down.
You don't know what's out there until you go look for it.
