I'm not sure I understand this whole thing about having the windows open. Why is that unusual? Mine are open by default, except in the office where the balmy breezes tend to disrupt the stacks of papers. Every month of the year. What's the BFD? How about your toilet lids. Are they normally open? Normally closed?
Oh, and your kitchen cabinets? Chimney flus? SIlverware drawers? Working peanut butter jars?
