If I'm down wind of you and I smell you, you are an evil person and I hate you.
If I walk through a place and I smell where you have been, you are an evil person and I hate you.
If I order food and I can smell you on my food, you are an evil person and I hate you.
If I'm walking through a place where you were once standing and I can taste you, you are an evil person and I hate you.
I don't care if it's BO or perfume or lotion. You are an evil person and I hate you.
