Regardless of who wronged who, it is messed up in my opinion to not go to her funeral. That's like getting the last laugh on something that is trivial, but inflates your ego temporarily. You have to also think about your family and how they will view you if you do something as spiteful as not going to her funeral. There must be children somewhere in your family, what kind of example does that set for them? Maybe there is a mom or dad still alive, to them you are their children, no matter how old you are now, to them you are still their children. How would you like it if you were in the same situation? Lets say you get into a horrible accident of some kind, and YOU are the one that is dying in a hospital somewhere, what would happen if you received a gift or a card from her? In all, I just think its rotten to do something like this to someone you once loved and are blood. One day, maybe not soon after, but one day you will regret not going. For one of the reasons I have mentioned or even other reasons. I think you really need to be mature when it comes to something like this, because in my opinion its childish. That is my 2 cents on this. You don't have to accept my opinion, but you are the one that asked the question here on this.
