Excerpt from this article:
Within five minutes, one of the counsellors on duty will write back… It is important to type carefully. In text messages sent to friends, typos can be an indication of intimacy. But a typo appearing on the cell-phone screen of a distressed teen-ager can undermine the sense of authority he’s looking for. “You have to train yourself not to hit that return button automatically,” a sixty-year-old counsellor from California told me. (Crisis Text Line counsellors are free to give a real or assumed first name to people who text in.) It is also regarded as a mistake to embrace teen-age patois too enthusiastically. One volunteer told me that she tries not to use acronyms. “I sometimes worry that it would come across as too ‘Oh, I got you!’ ” she said. Neutral language allows the texter to feel anonymous. These people have contacted a stranger for a reason. They aren’t looking for friendship.
