Have you had anything leak out about you that you hadn't intended? Something your colleagues found out that you had wanted to keep personal. Or something your significant other, kids, family found out about you? Or are you a wikileaker yourself??
One of mine, albeit minor, occurs whenever anyone finds out I was a cheerleader in junior high school. Whoops, there, it's out. Though I am surprised and kind of proud that my feminist mother and egalitarian father "allowed" me to be a cheerleader... cringing as they both must have been until I found tennis. I think about all this anew with my own daughter.
Oh, and future wikileaks on my horizon, when my kids find out I drink a LOT of diet pepsi.
