No seriously

Well, thank you. Very kind of you to say.

I will never forget, during my first visit to Europe, 33 years ago, sitting in a train compartment, listening to the five other occupants arguing heatedly in English. It took me more than a few minutes to turn from the course of their argument to wonder at five non-native speakers of English pulling this off. (I can only dimly recall that one was a Finn and another a Frenchman.)

And, let me take a moment to compliment you on your excellent English. At times I forget it's not your first language.

Ceci n'est pas un seing.
