I love visiting Europe. So many wonderful places. so much history and so many pleasant, kind and engaging people. Don't expect to always hear English, or to be understood everywhere when speaking English, even in England! Today Europe is a melting pot, more than ever, but most people try to be helpful when you get in a bind, just as they do here in the US.
Always find it interesting how difference countries solve their daily problems, issues with solutions that we may NOT be familiar with here. Readers can relate how different European cars are, and the respective driving experiences they offer, not necessarily better, just different. Same applies to many issues, transportation, eating (and drinking) out, accommodations etc. Sure, it's easy to mistake the negative behavior or attitudes of one individual you have the misfortune to experience with the country at large, but limiting your exposure by tarring everyone with the same brush will restrict your opportunities to learn, have fun and form new relationships, even if you comfort level is stretched.
Taking the same message when I visit friends on my next trip to Europe this year. Anticipate there will be many inquisitive enquiries and conversations regarding visiting and living in the US too.
