I am totally a messy person. My clothes go where ever I take them off until it's time to wash them. I almost always have a pile of dishes in the sink (though i rinse them so there's not food and it doesn't get all smelly) and I very often forget to take the recycling out. My house is a disaster, but I'm comfortable in it so I don't see any reason to change it. I clean when I need to or when I feel like it.
My boyfriend on the other hand is a total neat freak. He likes everything to be organized and in it's place. He used to work his butt off keeping this place spotless, but he's slowly giving up that fight. It's not like it's dirty, just a mess and disorganized.
