I'm sure I told this story before but since when has that stopped me...
We live in Scotland, my dad was born here but we are not from Scotland. When we moved here we did struggle with some language differences. People would ask "where do you stay?". I had no idea, I hadn't even told them we were going somewhere. Ah, it means "where do you live?"!
We were astounded, when walking my mum's dog in the park, when some children came and asked if they could "clap the dog". My mum's dog is like a helium filled fox, and we use time lapse photography to check she is actually moving. Certainly not the sort of dog that you would imagine could do anything that would attract applause from strangers.
Ah right, up here it means "can we stroke your dog"....
