Mistaken identity or words

My one boy is dyslexic/ has word processing issues which has not bothered him at all now that he is a little older and mad into numbers .... but one time when he was a young we visited a local village to walk the dog - Bradford on Avon. He threw a wobbly when we got there as he thought we were going to "Joseph and Nathans" we still laugh at it now but he was mighty upset at the time.
