What do you think is the worst thing to step on while stumbling around the house making your way to the toilet at night in the dark with nothing on your feet?
I say an upturned plug or a chunk of cat litter.
I woke up in the middle of the night to go the loo one time, didn't bother turning the light on and my foot sunk in to a pile of diarrhoea the dog had kindly left on the mat. I nearly got sick haha.
In the House ....Bobjugs ....in other distant places you would be right unless you brought home a souvenir and leave it on the rug in which case apologies
