Before this I was doing it. ( not cry but thinking ) . After that when I realized that it hurt you so much each time I talked about her and at that moment I just wished that I never had a good friend like her and thanked to have a special friend like you. It's not that I don't appreciate the present but sometimes the Smile, gesture, talking style  or even same dialogue just make me to think or talk about her to you ! I know you ain't want me to think about a person who don't deserve me but memories do not fade right. It takes time to forget someone who was once very close to me :)
