Today's Bangkok MRT trivia question

[francois]

I always type blind, I never ever lay my eyes on the keyboard, however yes sometimes we do make a mistake or two, as my typing speed is very very high. And yes I do work in the software industry, about 25 years now.

For clarification, when you type blind, do you not look at the screen as you type? I as assuming that matt cannot see the screen or , if so , only partially.
