Certainly the mental anxiety has something to do with it, but perhaps an equally challenging factor, one that is completely beyond our control, is the fact that the real world is a much more difficult place in which to wear heels than is the home. I must have said it at least a hundred times, but it bears mentioning again: I don't how many hours you've spent in heels at home, how many floors you've mopped, how many meals you've cooked, or how many dishes you have washed, the minute you step out of the car, take your first half dozen steps, look up and realize that you're going to have to cross the entire Walmart parking lot, and you will have to do so all in one go, while trying to act naturally, it will feel as though you've never worn heels in your life. Three inch chunky heels are definitely a good idea for those early days in public.
