Very boring...but what to give an absolutely fabulous temp' head teacher who is leaving?

I've never met anyone who gives so much of themselves to job. She has been an absolute breath of fresh air, and has always made me feel like my children are her priority.

Obviously I will put this in writing to her.....but also want to give her a gift.
Hmmmm.........

A card with exactly what you said. Heads get a lot of stick and just to know that they were appreciated would be great.
What about a High Street voucher?
