RULE # 1:

I have decided the most important rule to have in a share flat is this:

IF you use the toilet and the water changes colour, YOU MUST FLUSH. If you've been drinking water only for the last week or pee 10 mL or less and no one can tell anyway, fine, leave it.

BUT if you've been drinking beer for the last 30 hours straight and have kidneys on the point of collapse and the water is a murky yellowish brown colour, I think FLUSHING IS A GOOD OPTION.

DISGUSTED. ABSOLUTELY DISGUSTED.

I have a good mind to take a photo of the toilet with discoloured water, get it developed and stick in on my new flatemates' door.
