So, do you? I like it when people leaves a message or text me if it's important, and especially if it's from someone that knows that I don't have their number. If I have a missed call from an unknown number, I most likely wont call back. Either they dialed wrong, or I'm thinking that they'll call me again if it's important. And I'm getting annoyed that some call me with a hidden number, don't leave a message, don't send me a text about it, and then they're like "Why the hell didn't you call me back??" It may be hard to believe, but there are others that call me too. So how was I supposed to know? Leave a message!
