I don't know what's run away with my mind. I was writing checks, and I needed another pack, beginning with number 1981. However, the last check I wrote on the old pack was number 1979, and I have no idea where the hell check number 1980 has gone. I reopened the envelope with check 1979 to see if I had by chance put 1980 into the envelope was well. I hadn't, so I don't know where the fat hell it is.
