I'm in 9th grade and I went to all my dances dateless. I don't think आप should worry about dates to dances until your senior homecoming in high school. Really there are और important things आप can be worrying about.
Dances are not a thing at school where आप have to have dates या your a complete loner. No, it's a place to have fun and dance and do other shit. Sure, you're फ्रेंड्स have dates, but that's an optional thing, really. Even if all your फ्रेंड्स have dates, it's not the end of the world. Go with your फ्रेंड्स even if they do and hang out with them-if they're your friends, they'll hang out with आप just as often as their date. या there's dancing with another guy there-not everyone is going with a date. या even dance alone. It's not going to hurt if आप don't have a date, so there's no need a worry. Just have fun!
