Life is to short to hold a grudge. How many family members or good friends separate themselves because of some silly non-issue. I have made this tragic mistake and have decided I get nothing out of holding a grudge except a hole in my life. I have tried and failed to make amends because the other party still is upset, but at least I tried to make things right. I think the emotional and physical negatives of staying perpetually pissed off at someone close are just to high, holding a grudge is like having gas, you feel better when you let it go.
