Am I missing something? I thought Valentine's cards were for 'lovers' or admirers to send to someone you think of in that way? Before this opens a deluge of people decrying them anyway, we were married on Valentine's Day, and it is therefore special to us as both our anniversary and a day for people who love each other in a non-parental way.
Anyway what I'm rambling my way round to, is I was choosing an Anniversary and a Valentine's card for my husband (he may be Victor Meldrew in many respects but we still like to be romantic with each other). In amongst all the Valentine's cards for partners etc, there were cards saying 'to my son (or daughter) on Valentine's Day. What on earth?????
