Jackie and maverick, Thanks for the help. If you'd been looking just now, you'd have seen that I duplicated the post...and had forgotten that I'd already 'sent' the link! Yes, I'm old, and I'm losing my mind!
I had a birthday package for my son-in-law with several cards sitting in the box. The weather forecast is so dire, I decided to mail it today, so I quickly sealed the box and brought it to the PO. When I got home, I typed to my daughter..."send back any unsigned cards, and I'll use them at future appropriate times"! Did I, or did I not sign/send a birthday card? OOPS.
