Self: when you live in a place with a small bathroom, be sure to keep the toilet lid closed. It’s really easy for things on the sink, medicine cabinet, or shelf to fall into the toilet if you don’t. Like your hairbrush, when you’ve got your head upside down, blow-drying. This is even more gross than it seems, because your hairbrush, full of hair and styling product, becomes really slimy when you pull it out. Really, you should just go buy a new one anyway.
