Someone else said something like this elsewhere: Pause, and think, before we hit "send".

Long ago, when I was in jr. high school, I told a girl I liked her. For a few days afterward, she and her friends mocked me. I felt like the whole school knew about it. But, it was a large school, and most of the school didn't know we existed.

Nowadays, with Twitter and Facebook and other social media and e-mail, the whole world "can" know about it.
