I have endless hours of mirth sipping coffee in the morning sunshine and watching Americans trying to negotiate Sarlat market.
I know many of the stallholders have at least a smattering of English but a loud and getting louder by the monent american always brings out the french in them.
When I was in Paris the first time, I spoke French well enough that people wanted to speak English to me.......they knew I was trying, but didn't want their language murdered.
