As of a few days ago I am the only girl in my class who was not asked by anyone. What do you think about going alone, is it a good idea?

I have gone alone to school dances. Everyone in my group was a couple but we were all friends. I actually had a great time! It is something I look back on and smile. I think you should do whatever you feel comfortable with. Expectations can leave us feeling like we are missing out on things. Sometimes this can hold us back because the idea has changed or been altered from expectation. Don't feel socially pressured either way, nothing is guaranteed. I've seen many people who have gone with someone have a terrible time and so on and so forth. If you want to go to this dance, you should go!

I am writing under the assumption that you are referring to being asked to a dance. It is 100% a good idea to go alone to a dance if you feel happy and confident about it! There is no rule book that defines what you need in order to go to a dance. If you plan on going to a dance, all you need is yourself, maybe some friends, but most importantly a happy spirit! Going alone means that you can spend more time with your friends and simply have fun without having to have your toes stepped on by a date of yours. The end goal for anything is to have fun and relax, and you certainly don't need another person to do these things! I wish you all the best!
