Witness PS This kind of cinical use of peoples altruistic tendencies is unfortunately all to common here in the UK. as a trivial example; yesterday I was in my local super market and a person dropped some shopping in front of me. I picked it up and handed it to them. they took it from me without saying thank you or smiling or even meeting my gaze. This won't stop me doing this in future but it is very sad. The same kind of thing happens far too often when opening doors for people as well. I think some folks took the previous Leaders dictat ; "there's no such thing as sociaty" too much to heart. Keep the faith all the best PP.
