I like to think of small puddles of piss, dotted about at random, as gifts that DS1 has given the world. Not sure whether I can rationalise small puddles of diarrhoea in the same way, however. For those, we just turn on our heels and run, run like the wind.
I am worried about you and your bookshopping now. Shopping for books is in the Universal Charter of Human Rights, surely?
