Jill, no unfortunately is wasn't said in jest.
Sue, that made me laugh, we are all over 40, three are over 50 and I'm over 60!
Trish, to be fair all the staff that are leaving have been there a few years and there is no pressure to contribute. I will contribute to the collection for one person I know well.
I don't ave any problems saying no, I refuse to join in with most things, I find this helps some people who otherwise would be too nervous to refuse.
And as for the matching red Santa dresses, I have a plain red dress I will wear.
