How to stop this fight with my best friend?

Oh, to be a teenage girl again. i don't know these kids but i will tell you to hang on. you hurt their feelings and now they kind of don't like you(but they will), so give them time to come back to their senses. they think that you were wrong for dismissing what they wanted to do, so, an easy way to fix this is (as much as this might suck) to suck it up and apologize to them. or if this fails buy their affection. it's wrong but when you're a teen, it works.
