Oh god, I'm almost ashamed to say I can't really keep a secret - especially my own. If you tell me something and then don't tell me not to tell anyone/that it's a sensitive matter, then it'll probably be mentioned casually if something sparks up a relevant topic. I don't go around telling everyone someone's secrets for no reason! I'm just a very open person, so I don't really keep my own secrets either. I think there's one secret I have where I've told a handful of people, but I'm certain others I haven't personally told know. I've never really had a secret that's been a terribly big deal, and I don't think anyone has told me one either. But I'll keep my mouth shut if you tell me to.
