Hello, Bonjour, Salam.
When you travel around the world so much, it becomes second nature to sometimes drift into constant English speaking. However, on my travels I always tried to delve into some of the languages that I need to speak to get by. Admittedly I am not a great language expert, despite learning Cantonese in Hong Kong and Spanish in Uruguay. But it helps to get you by if you can say hello. How can you be an International Master of Saying Hello?
