I understand and agree with your sentiment, but just don't buy the uni-tasker type lego. They make plenty of sets where most if not all of the parts are general and can be used for undirected play.
I’m up voting because I want to hear this side of the argument. I guess your point is that most people’s experience isn’t that bad, and they owe their parents.
Sure, so it can just be a matter of balancing how they treat you and your family vs basic decency and the benefit of merely maintaining contact and having them around as grandparents for your kids. Everyone’s experience and tolerance is different.
I don’t think we necessarily owe our parents. They made the conscious decision to have us and raise us, that ought to be a reward in it self.
I certainly will the best I can for my kids, but I don’t want them to think they owe me anything. This is especially true if I am (unknowingly or unconsciously) treating them or their family very badly.
