It's always good to know a few words in the language of the country you are visiting. The locals appreciate and warm up to any attempt by a visitor to speak in their native tongue. The Travel Linguist on YouTube has short videos for learning 10 "survival" words and phrases in 15 languages including Japanese, French, Indonesian, German or Thai, to name a few. These 10 essential words and phrases are possibly enough to win friends and make your trip doubly interesting and exciting. At the very least, you'll learn how to ask, "Where's the bathroom?" And you know that's an important question after having had too much red wine in Burgundy or chai in Thailand.
