I was waiting in a queue to use a cash point today, while a mother let her child who looked about 5, to press the buttons. The child kept getting it wrong, and so the mother urged her child to try again. Eventually an adult in the queue complained. And the mother retaliated with "Well he has got to learn".
No he hasn't. Not at 5 and not with a queue of people waiting.
AIBU in thinking this mother was BVVU.
