i'm a teacher and i think you should give a pressie
even if it's a homemade card or picture, it's nice to show your appreciation.
the best pressies are:
wine
smellies
christmas tree decorations
children's story books
other alcohol related products
i'm not that keen on receiving 30 boxes of chocs tbh but then i have no self control.
best ever present was a pair of black velvet reindeer with neon pink horns and glittery backs. they are so tacky kitsch. they get front stage on my fireplace every year.
also, you can't help remembering what people give you and although i don't judge (honest) i worked with a lot of people who did.
