Text messaging has become as much a form of communication as an old-fashioned phone call. What's different about texting, though, is that it's a (mostly) silent activity that can conceivably be done on the sly.
The subject is all over the news, too: The New York Times just reported that there's a ban on federal workers texting while driving, and the Today show recently ran a segment about parents who set texting rules — specially during meals, vacations, parties, and other family time. I personally cannot stand talking with someone who's texting at the same time.
Texting at the wrong time can be rude, distracting, and in the case of driving, downright dangerous. Are there other texting situations that drive you crazy?
