To the girl who ruined prom for my cousin,

Once upon a time, the three of us were friends. We had fun memories together and shared important milestones. Because of this, you shouldn't have ruined prom for my cousin when it was me you hated. I took my cousin to my senior prom because I didn't have a date and we decided to have a blast together. The senior prom is a time for moving on and celebrating graduation, not stirring up drama with someone you hadn't talked to in two years.

On the day of my cousin's high school prom, one of her friends was murdered at her school because she said no to a prom-posal. This tragedy really shook my cousin and she developed anxiety about going to my prom. The only reason she still went was to get her mind off of the loss and to have fun with me. Instead, she was painfully reminded of her friend's death. By you. Now I know this was two years ago and should be water under the bridge, but my cousin said something the other day that reminded me of how badly you hurt her.

If you truly wanted to express your condolences or ask how she was doing, you could have Facebook messaged her. You could have texted or told her in person at a graduation party the three of us were at. Instead, you purposefully waited until my cousin was at our prom to go up to her and bring up the tragic event. Maybe you didn't know how badly it would affect her, but I seriously doubt you had anything but malice in your mind. It was me you had an issue with, and you ruined my night because you ruined hers. You won.

She spent the rest of the night not being able to dance because she felt claustrophobic. Her anxiety came on so strong because she was so bothered by what you said. I sat with her at our table for most of the night and you know what, I'm not even mad that you succeeded in making sure my senior prom wasn't great. I'm mad that you got to my cousin and made her miserable to hurt me. She had to talk me out of punching you and making a scene. I didn't care if I would get kicked out of prom for it. You had a problem with me -- ruin my night, but how dare you go after hers?

I'll never understand why you felt the need to ruin someone else's night instead of enjoying your own. You must have seen an opportunity to make yourself feel better and that's sad if you achieved that through my cousin's pain. Your actions were unjust and you really hurt someone you used to call a friend. However, you didn't break her or me and instead, we got even closer because of you. Prom of my senior year certainly sucked, but hey, now it's just a story to tell.

If you ever feel the urge to ruin someone else's night again, don't do it. You never know what that person might be going through.
