I wonder how long I can sit here quietly before someone asks something of me. I've been sitting here for about twenty minutes and several people have passed by without looking at me. Trying not to make eye contact is the hardest part. If I do, someone will surely ask me to do something and I am having none of that.
Maybe if I keep looking intently at a page with some writing on it and frown people will think I shouldn't be disturbed.
This is working out pretty well.
