You're certainly not on your own, mrsO, we agreed some years back that we wouldn't "do" Valentine's Day - there's no need.
In my youth, it was about sending cards anonymously to someone you fancied, if you received one you were thrilled to bits - you never got one from people who gave the card or flowers to you, the mystery of the donor was what it was all about. It's too "in your face" now.
