I always set my phone to buzz at 45 min, so I know it's almost done. I freaked out when XT held me over, so I understand. I don't want to be one of "those" people who won't end either. BUT... you are not staying over. You are not "stealing" his time, he is giving it. If you were the type of person to push boundaries, he most likely would keep his. One time I called XT in a crisis. We talked on the phone for a bit, I was really conscious that I was stealing time from him, and instead of hearing him I was freaking out. He persisted until I finally calmed down. When I hung up, I realized we had talked for almost 55 minutes. I freaked out, and tried to pay him for it at the next appt. He said, "wiki, you didn't steal my time, I gave it to you. You'll just have to suck it up and accept my gift". Still bugs me to this day.

Believe me, you'll never be one of those clients that finds excuses not to leave, or lingers around. You are too conscious of NOT being one to be one.
