I just don't get the need for it. You can be chic and glam without smelling like civet pee and artificial violets. Stuff can be clean without smelling of vile air freshener or pot pourri.
What would be wrong with just smelling like washed clothes, washed hair, and some plain soap?
Several of my students wear perfume so strong that my eyes water and I get a headache just being in the same lab as them. It's the female version of Lynx for teenage boys (which I don't get either).
OK I am an extreme case because it gives me severe migraines. I'm currently awake trying not to throw up after spending the afternoon with the two perfume-clad students.
Why do they torture me thus? Why?
