I hate

Well this is the thing, its alright if you take a bit of milk, but the very last bit!

Its an unwritten rule, you just don't do it :)

We share milk, well, I share milk it seems. I buy 2ltr at a time, my flatmates both get 1pint max at most every other time.

I Often get milk which I never see, or worse, I find it opened, 4/5 full, left out the fridge all day.

Now and again I've taken to pouring full fat cream into their skimmed pints to sabotage their diet regimes.
