For Because of this, I try to keep my room as clean as possible, although I know it can be a mess sometimes. Once in a while I clean out my room, I put many things outside of it to make cleaning easier and air it out. If we talk about my sister's room that's another thing apart. Her room is a disaster area almost ever complete disaster, her room it takes much more time to be clean than mine.That's why she likes others to pick up stuff after her. I think she really does the chores and I just tidy up.
