Don,
All parents want their kids to have it easier and better. If you have a close relationship it makes it even better. I do not feel you can tell them or others enough. So no, you do not say that too often.

My son is in his early-mid 40's and due to distance (he lives in another country due to his job) I have not been able to see him very often in the last 10 years. He is into Vesba's (sp?). At least it still has a motor and wheel's.
