Just in case you haven't seen the posters, public service announcements, and radio commercials (I guess you hear those rather than see them) about the dangers of texting while driving, here's what they are saying: DON'T.
But also, if you are an uncoordinated clown like I am, refrain from walking while texting. Because while it may not lead to automotive chaos and destruction, it may lead to you walking through the airport, on your way home from somewhere, feverishly tapping your thumbs in a humorous story to someone you could tell that story to in fifteen minutes, and then walking onto the little airport tram without hearing "The DOORS are CLOSING and WILL NOT reopen".
At which point the doors WILL close, nearly snipping off your nose, and you will look up startled and see a tramful of people snickering at you, as you stand on the wrong side of the doors (fortunately still in possession of your nose), reduced to waiting for the next tram.
And feeling silly.
(Which you will then text about.)
