Trying to find a date for prom can be one of the most stressful experiences in a high school student's entire life because most high school students haven't experienced enough actual adversity to realize who they go with probably doesn't matter in the long run.
I was lucky enough to never have to worry about finding someone to go to prom with me. Thanks to the social anxiety that plagued me throughout high school, I was more than happy to fly solo my junior year -- an experience I then used to justify skipping my senior prom in favor of playing "Call of Duty" in my basement for four hours.
On the bright side, at least I didn't have to worry about the potential awkwardness that comes with meeting your date's dad.
You don't need to have a date to have fun at prom -- sure, you might be decreasing your chance of doing some hand stuff in a dark corner later on in the night, but you're honestly not missing out on much.
These people might have technically gone to prom by themselves, but they all managed to make the best of the situation.
