A best friend really fell out with me over something stupid - we've made up but i'm still a bit mad with her?

having misunderstanding is not something strange but the ability to dissolve the misunderstanding pose a great treat to many.... in friendship there must be mutual understanding between the parties involve.. call her attention and have a heart to heart talk with her.. there might be something else eating her up other than what happened.... explain things to her, if she is not complying give her a break to think things over, if she is still interested in the friendship, she will come back, if not let her be
