email is fun!

By far the most interesting habit that children have when they're in
the computer lab is when students sitting near each other, even
adjacent to each other, will email back and forth (via a free
web-based account). This even happens when the room is filled with
noisy chatter. And no, they aren't engaged in quiet discussion about
a private, personal matter; most of the messages to the friend next to
them are of the "HI THERE. DIZ IS BOORING" nature.
