I'm living with 5 roommates right now and 3 of them eat cereal with me in the morning. However, after they finish they just leave the bowl in the sink and fill them with water. I don't get why they do that. I just rinse out my bowl afterwards because it takes 10 seconds to do so. I don't see how filling them with water is supposed to help since it's just milk and rinsing the bowls is enough to clean them.

Anyway I eat Oatmeal Crisp (Maple Nut flavor). My favorite cereal by far.
