Overnighter

Sorry about the lack of a post yesterday. It was Valentine's Day, and I was busy pretty much the whole day.

Today's question is a little bit more random, so get ready for this!

Imagine for a moment that you needed to pack an overnight bag, whether it is for couchsurfing, going to a wedding out of town, or simply having a sleepover with a friend. There are two limitations: everything you pack MUST fit in a single bag that you own, and you have to make the list for someone else to pack for you. What do you write down? What is missing in the lists that others have posted?
