A perm. I wanted one so bad when they were popular in the late 80's. All my friends were getting them but my mother wouldn't let me. She told me that I would "thank her someday". Now I do. When I look back at pictures, I see my 7-year-old friends with puffy hair. They're hair is still damaged from the chemicals used.
I also wanted the game Mall Madness but my mean, mean parents wouldn't get it for me.
My grandmother felt bad and bought it for me so when I went to her place, I played it there.
