I had such a good chuckle when I read this one! I do not know what it is with girls and hanging on to grudges, but this pretty much sums up what happens when girls have a serious fight. What constitutes a serious fight? That will depend on the person and what is important to them. I, personally, think that the reason girl fights are never over is because we involve other people and discuss the in’s and out’s of why we are annoyed with the other person. You may be talking to someone who does not particularly like the other girl who you are fighting with and when you are upset the last thing you want to hear is the voice of reason. What you really want is someone to agree with you and your reasons for not talking to whoever else is involved.
If you choose to get over things then the last thing you should EVER do is launch in to that topic again. It is like opening a can of worms that you should have gotten over whether it was easy to move on from or not. The main problem with girls is that they can be very competitive, jealous, vindictive and selfish when it comes to their friends. Those qualities may creep up when you least expect them to. I would not say that it is impossible for girls to overcome their silly fights, but you have to be willing to forgive and forget!
