My room mates are messy, any advice?

Have a meeting with the two of them, and say hey three people live here, so we all have to be respectful of each others space...therefore we need to work something out...you dirty the dishes, you clean them up." 19 is really young, and they are still used to living with their parents. They just need to understand that three people live there, and it is not their personal space, they only own a third of it. I know, it is super uncomfortable to someone about taking out the trash, and keeping their mess out of sight, but it needs to be done. kids will always ignore notes, the only way is to confront them. Don't yell just suggest working out a schedule or something for who gets to do which chores, after all three people do live there, therefore it is all of your responsibilities to make sure it gets done. Then post it on the refrigerator, and make copies in case it "magically disappears" You are completely within your right to be upset about their slobbish behavior it really is immature of them. If they want ot be messy then they can do it in their room, but living/kitchen/dining rooms are a community area not their personal space and they should know automatically to keep it clean.
