I looked after a friend's 3 year old this morning.
She can't pronounce Hobnobs so just calls them nobs, which her mother doesn't discourage because she thinks it's hilarious.
We went to Tesco, the local Tesco that I regularly shop at where people know me. Several hundred people overheard her shouting at the top of her voice at a million decibels how much she loves nobs.
She told the woman at the check-out that me and her were going home for a cup of tea and some nobs. Then she told a different check-out woman that brown nobs (chocolate ones, she describes all foods by their colour) were my favourite.
On the bus back to mine she asked me very loudly if we could get the nobs out. Two women chuckled so I said "It's Hobnobs remember" just so they knew what she meant. This made the women laugh more, which made her just start shouting "nobs nobs nobs nobs nobs" until I physically man-handled her off the bus.
Fucking hell. I'm thinking of refusing to look after this child until she speaks with perfect RP to save my blushes!
