I think the chances of your PP showing up at your home are pretty slim.I send pictures to my two PP's all of the time .If you feel worried maybe just get a PO Box and ask them to write you there.Maybe you could say you were going to move.Im not really sure about how to take your adress back.I have always had a PO Box.I am quite sure you will be just fine.My grandmother gets paranoid as well.I think the media has lead so many people to think that everyone in prison are crazy killers.I was in prison and I would have never showed up on someones doorstep.I had just got out I wasnt about to go back in for some stupid stuff.
