What can you do if you forgot deodorant and you're starting to sweat?

Right now, you can either go to the bathroom and wash your pits a little, or you can avoid doing a lot of things so that you don't sweat a lot. You can also keep your arms down so that any smell that is there doesn't spread.

Something that you can do for the future is to put an extra deodorant in your backpack or bag so you have some with you if you forget, or you can take an extra to keep at school or work.
