I have just returned from a morning out, shopping in town. I can handle this pretty well, but there is one area of town that I can't even contemplate entering, and the reason for this is because it can only be accessed via an escalator. Whenever I am on one, for some reason I feel as though my knees are being forced in the direction of where the stairs are going. I usually end up in a pile at the bottom of the stairs, and various other shoppers seem to assume that I have just come out of a bar! This is very embarrassing, so I just ignore that side of town now. Does anyone else have this problem? If you do I feel for you.
