that is so heart touching...i got a sister, (i'm telling everone now about her) and i feel the same about her...we promised that we would never fight again, but they just keep coming in-i took in some advice from chicken soup-although i dispise living off a book-this one chick said to another,"You're my friend, Katie, but we just don't fight enough to be BEST FRIENDS."...so yeah..a lot of fights do question a friendship, yet it can also improve one.
