I have a yellow sheet of legal pad paper, where I keep track of all my submissions. I check the sheet every night to remind myself of what I've sent, when I sent it and where I sent it, and the result. But after mailing my Mom Dot Com story to Lee and Low publishers, the sheet has vanished. I think I may have stuck it in the envelope! Hopefully they'll use the SASE to send it back.
There are some disadvantages to having a day job and writing into the late night hours! And to being old, I guess, although in so many ways this is a terrific time of life.
