history: I just cleaned out under my bed in order to do a bedroom make over and there was so much dust and old stuff under it.  Yesterday I was preparing to paint my bedroom furniture and I unearthed so many dust bunnies from under my bed! It's never too late for some late summer cleaning!
current: Yes I should have done this a long time ago! 
next: Sounds like it.  Are you going to sleep better tonight knowing its clean?
