tiggs, your first line reads they were friends, when you found your loo upstairs full, you said "it'll teach you not to invite people around', it wasn't people, it was friends and one friend had a bad tummy, probably moritified so went upstairs rather than the 'guest' toilet downstairs - just let it dissolve in it's own way, ya never know, one day it could be you, and your friend posting here or on twitter, we have no control over the bowels - don't judge that person, getting short taken is so mortifying
