Well I know I don't, not if I can help it and certainly not in 4 inch heels. I stay within the 2 to 3 inch range. But Paris Hilton is of different breed, I must admit and stop hating. Perhaps she was looking for a BFF for her new reality show, somewhere between the dairy and bread aisles. Looks like the first time she's pushing a cart as well, everyone learns by trial and error.
