A thank you

Isn't it nice to be thanked from time to time? On Friday I spent half an hour explaining some fund management industry jargon to G, who is on a temp contract with us. Apparently she'd asked some other people who had always been "too busy". She was so pleased that I'd helped that she bought me a little present... So that's the first time I've had a present for doing something at work. Let's just hope that everything I told her was correct....
