This morning I was sure I'd nailed all the problems. Fries had become chips. There was no mention of baseball. Mom was now Mum. Oh, and 4000 words was now 2000.
Feeling proud (sorry, feeling chuffed), I printed the story, and only then did the funniest error occur to me. I am a music teacher, and this story deals with music. But I had not thought to change the American "eighth note" to the British "quaver" or "sixteenth note" to "semiquaver."
Oh, well. I caught it just in time and reprinted. Sure hope this finds a home in a Brit-influenced land, but it was a fun experiment in any case.
