Smells
You know what I was just thinking about... smells. Like, my hairspray is one smell, my spray deodorant is another, and my aftershave is another. Since the fragrance fades, I can only smell one at a time. But I have no clue what it smells like all together, which I assume other people smell when they're within a certain radius of me. It makes me wonder if the combined smell is good or bad...
