Summarize the following:
The sign’s message doesn’t have to be complicated. It can be a simple “Will you go to prom with me?” or even just “Prom?” If you want to write something more involved, spend some time thinking about what will be easily understandable, what will fit on a sign, and what you wouldn’t mind other people seeing. A very personal anecdote, a long story, or a really obscure in-joke may not work out very well.  You can also decorate your sign with glitter, photos, or balloons. Try leaving your sign somewhere your date might come across it on their day-to-day lives. Make sure you put both of your names on it if you do this! Why make a sign when you can wear one? Write your promposal on a shirt or a baseball cap and wear it to surprise your date. You can do something simple like writing "Prom?" on your shirt, or you can even have a custom shirt made for both of you as a souvenir. If you and your prospective date love a crowd, try promposing with your sign at a big event with everybody you know present. Any lighthearted or fun event is fine to choose. You can pick a sports game, a pep rally, or even just a really crowded hall or lunchroom.  Avoid formal events like speeches and plays. You want everyone to be thinking about how cool your promposal is, not wondering why you’re interrupting everything. Definitely don’t plan a promposal at a sad event or a party for someone else. If your school has a marquee at the entrance or in the sports complex, get your promposal on that sign! Find out who's in charge of the marquee and ask if you can use it for your promposal. Remember to include both your names!
