Design, to me, is part psychology, part sociology, and part magic. A good decorator should know what's going on in someone's marriage and how their kids are doing in school.
I made my parents crazy. As a kid, I redecorated my bedroom every month. I would literally save my allowance and go buy things.
As a kid, I think I rearranged the rooms of almost every house on the block.
I think I was the only kid on the block who knew about furniture scale by the time I was 8.
Some kids spent their allowance going to see 'Indiana Jones and the Temple of Doom'; I spent mine on a great-looking lamp I'd found at the flea market and a ceramic bowl from a neighborhood garage sale.
