Well, there's VM. Leave a message and tell me what you want-- did you need to talk about something in particular, or did you just want to say hi and shoot the breeze? "Hey, I wanted to ask you about the baseball game this weekend" or "Just wanted to say hi, no need to call back..." The people I would like to throttle are the ones who call you and call you and call you if you don't pick up right away instead of just leaving a friggin' message.
