How to save a friendship?

<p>Ok, well I am a freshman in college and there is this girl who I have become good friends with. We talk frequently, and i really like being around her. However, a couple days ago, we were hanging out and just kinda joking around with each other. We normally don't mind lightly making fun of each other. She made fun of me for messing up on a calc test (ya, I know...we need better things to talk about). I laughed about it and then jokingly said something about how she messed up a speech she had to give in another class. She, though, didn't take that joke well. She left the room quietly, making me feel bad about the whole thing. I later called her to apologize and she just said she didn't want to talk to me. Now, she won't acknowledge me when I see her around campus/in class. Is there something I should be doing to fix things now or is this one of those wait and see kind of moments?</p>

<p>I would text her/facebook message her as it is less confrontational than a meeting in person or a phone call. Just say something like, “I am really sorry about what I said earlier. I honestly meant what I said only as a joke and nothing more and I did not mean to hurt your feelings whatsoever. I hope we can still be friends and I really value you as a person.” Hokey, yes, but pretty straight to the point. If she is a good person who also values you as a friend, then she will come around eventually. If after text or facebook message she still hasn’t responded for a while, don’t bother. If she doesn’t respond back then she is not worth having as a friend anyways.</p>
