I was with a colleague in the local Sainsbury superstore and we heard a young mother, who couldn't be more than 18 years old, berating a youngster, a lad of maybe four years old.
He was clearly distressed and unfortunately, his cries were getting through even the apparent soundproof wall that some parents seem to be able to erect at will. So much so that the girl I assumed to be his mother had to raise her voice to that of a screeching harridan.
One comment caused me some concern:-
"If you don't f***ing well shut up you little bastard I'm gonna sell you on e-bay tonight and get pregnant and get another baby cos you're not worth the money you bring in anymore you ungrateful little bastard."
The above verbatim as far as I can recall.
