Sometimes it's harmless - a "what's up expletive " meant for your best friend but accidentally sent to a cousin you don't speak to often enough to use such profanity. Sometimes you mean to send a crude joke to "Dave," but sent it to "Dad" instead. Sometimes you send a massive text to a dear companion divulging your secret love for a longtime crush, only to have actually sent it to your crush I've done that - mixed results, gents. And sometimes you mistakenly send a naked snapshot meant for your partner to someone who just so happens to be more than willing to immediately post it online. If you're a regular person, it probably won't be met with much fanfare.
