My parents used to complain a lot about how much they sacrificed for me and I didn't get it. Well now I do get it that I have a son, but I'll never say that to him. He is only 4.5 so we will see. I just don't want him to feel that he owes me anything. He doesn't owe me anything. Whatever I do for him, I do so willingly and the result is all mine to take, good or bad.
