i know what you mean inkblot, whilst sleeping on the streets in london i would read a book so i would not have to interact with the pack rats walking past me everyday and night yet they still didnt get the message and would stop and ask me benign questions, offer me food and drink even if i had some next to me, but the worse thing they could do was stop and take a photo of me from accross the street whilst they thought i wasnt looking, i used to jump up and ask them if they thought i was a tourist attraction and if so i want payment for copywrite for the picture, most had digital cameras so they deleted them whilst i watched.

what most of them fail to realise is they are only one paycheck away from your situation. so next time someone bothers you tell them just that, they wont bother you again
