oh dear!
Psyhco flatmate, or workmate?

workmate... i think she's at the end of her tether!

but quite polite ........

hahah why not replace all her milk with non organic, and see if she notices the difference.
you could drive her mad slowly

It'll all come out in the wash. Karma - eventually a herd of cows will invade the office and trample on the perpetrators of this evil crime.

I'd be worried if your flatmate started writing 'Ruth' on cartons of milk...

yeah, it was bad enough having him writing it all over the windows.

i was wondering if it was tef's idea of a joke.... actually, i didn't know if it was just the two of you there!
