Well it certainly didn't happen when I was a young kid at school in the 50s and 60s, so far as I know, in my area it didn't happen in the 70s either, scuse me peeps, but I think this was something started in England and I've never seen the need for it. Teachers are doing a job they are paid for, so who thinks they should get gifts from children anyway - I don't get it, and I'm not tight, I just don't get it.
As for Q - I wish they would shut up about it too, but remember they are selling, so what better opportunity than to suggest "now this would make a lovely gift for a teacher, don't ya think"?
