So "I cannot copy for myself' called me again to say, "Do I mail things myself, or do you do it for me?" I responded, "Typically people here mail things for themselves, so yes, you would do it". The conversation progressed a little like this:
Old Guy: I have an envelope and these signed letters, so now what do I do? I know, I'll fold them up and put them in the envelope
Me: Have you addressed the envelope?
Old Guy: No.
Me: Ok. So you need to start by addressing the envelope. If you don't address it then it won't get very far.
Old Guy: Ok. Then what?
Me: You then put the letters in it, seal it up, and take it to the guys who put the postage on it. They'll then put the postage on it, and it'll go out.
At this point I could literally FEEL him wanting me to do it for him. Had he asked I would have, but I'm just not going to play this sort of passive aggressive game.
So, Old Guy, mail your own letter. This is just not that difficult.
