In Thailand, if you only know English, you will have problem interacting with the locals. Any locals who works in the tourist industry will know some English. But most others dont.

In Malaysia, you have a higher chance of being able to communicate with a random stranger using English.

I have traveled round the globe and driven in almost every country i visited.

I will never ever want to drive in Vietnam. I couldn’t even cross the road.

I literally have to follow behind a local grandmother as she lead me across.
