Do this if you don't want me to like you, #32:
Say "Well I'll let you go now..." when on the phone with me, when I have given no indication of other committments or obligations at that moment. If you want to get off the phone, say "I gotta go" or something like that, don't make it sound like you're doing a favor by letting me off the phone! If I have to go do something, I will let you know. If you want to hang up, that's your issue. It's all about taking responsibility, regardless of the severity of the issue at hand.
On a lighter note, I have an appointment at the Aveda Institute for a hair-cut! Hallelujah!
