As for me, I've always believed that we owe our children everything, but they owe us nothing.
As a kid I knew we had a large large family and I also knew my mum and dad held reasons not to be close.
I later discovered that they both found it difficult to give in to the constant requests for emergency help. We didn't have much of anything really but it didn't deter the leaches from taking whatever they could get a away with.
