I know exactly what you mean. A friend of mine took me to buy make up and I spent about that same amount (honestly, I can't even remember how much). But it's all in a ziplock baggie and I've probably only used it about three times. I bought it a couple years ago. So I should NEVER have to buy anymore of it ever!! I only wear eyeliner and mascara on a daily basis.
My friend says, that's the price you pay to be a woman. Umm....ok.....NO!!
She also wears high heels and says the pain is the price you pay to be female. I do not, and never will wear heels. (Partly because it will make me taller than Bruce and they HURT!!!)
