Am I from outer space?

This is something I was wondering today when asking 14 year olds these simple questions
What is your name?
Blank face
How old are you?
Blank face

And we had just gone over these questions time and time again and the questions and answers are on the board. Believe it or not these kids have been learning English since primary school!!! Maybe I shouldn’t get so frustrated when I don’t understand everything, at least I can answer these questions in Thai!!!
