You don't want to laugh at the dead, and you don't want to make fun of the disabled. But it just strikes me that if you're deaf and walking along active train tracks, you really ought to make sure that you're
a) walking against traffic
b) walking far enough from the tracks that a passing train won't hit you, and
c) paying attention to your surroundings.
Text messaging when you can't hear what's going on around you (whether being deaf or listening to your iPod -- a pre-deafness condition for many) is not being aware of your surroundings. If it was in New York, it probably would have been a cab or a bike messenger instead of a train. But the lesson's the same.
