We all sound the same to them.

While in Corsica, people would regularly refer to us as "Anglais" and we got into the habit of correcting them (nicely) with "Irlandais". (Yes, yes, I know I actually am English, but Vic and Daisy are Northern Irish and they outnumber me. "Irlandais" is a correct description of the family.) Anyway, so one nice shopkeeper, explaining why she made the mistake, says, "C'est la meme accent."

Well, I found it amusing.
