No line at the PO - bargain! Pay 34c - easy.
Counter worker brings me a card and I leave. As I am walking to my car, I look at the card - it isn't addressed to me, instead it is for a neighbor. I almost leave and deliver the card myself (and would have if the line had been long), but I have received a lot of incorrectly addressed mail recently, so I go back in and gave the card back. The guy isn't sure exactly what to do, so I just say not to worry about the 34c (the beleaguered post office needs it more than I do) and go on my way.
I thought this was the end of the saga, but if you tune in tomorrow you'll be able to read the last installment.
