I didn't know I needed to justify my actions to you!
I was from top to bottom because I think it is silly to wash the dirt of one area of the body only to have it go over a clean area of the body. It is like washing a car - you always work from top to bottom.
I floss first b/c flossing loosens up gunk in between your teeth and brushing afterward ensures that you scrub that stuff off your teeth.
