I'm aware this isn't the right place to post but I wanted some advice about what you would have done.
We were out with friends a few months ago, they have a 6 year old dd. Friends are foreign. Let's call them Adam and Eve lol. I'm Friends with Adam and have met Eve on several occasions but don't know her well.
Eve says to Dd6 "what does this say"...Dd6 read it perfectly and pronounced it perfectly. Eve corrected dd6 for saying a local place wrong...(Eve pronounced it as it reads, rather than as its said). Obviously as I don't know her well I didn't want to interfere...but would you have corrected her (OK maybe not on front of dd6, but quietly to the side)?
I have several foreign friends and all are happy to get help with pronunciation or phrases...I just felt as I didn't know her very well, that it would be rude. I did consider trying to drop it into conversation, but I couldn't.
