Still learning

It gets me, still, that just getting a rise out of someone is such an integral part of this culture.
A couple days ago, walking down the street, I said hello to a student passing in the other direction.  Three steps later, I heard a frantic, "TEACHER TEACHER TEACHER!" so I stopped and turned around.  She waved me to her and said, in a timid voice, "where you go?"
And that's a perfectly legit activity: yell, scream, grunt, and holler until someone looks at you, especially a farang, and then pretend nothing happened.  Or look like a deer in the headlights of an oncoming English truck.
