I'm not sure you know, this is a tough and weird question. Frankly I like how my room smells as it is (I use a pretty neutral air fresherner/odor neutraliser but it generally will smell like fruits such as Kiwi or apple because I like to eat those regulary) I would say it's gonna have to be someone like Shlup because most teachers even supply teachers have to have a minimum standard of cleanliness.

On a side note, what would your smell be like? Personally with me it's probably going to be something like CKone or CKin2u for men because I wear that aftershave pretty much exclusively.
