Not everyone speaks English, and i think from the beginning it was obvious it was not a vid in English.
One language i love to sometimes watch is the clicking language. Yesterday i went through a gruelling interview about a drugs trial for three hours in French, even though i know that the doctor speaks fluent English. I know the terminology better in French, having learnt it over the past few months.
Some people love to learn languages, can learn them. And others don't and won't. Each to their own.
