I like to see the clock because I like to know how much time I have left. With this T, I use it to gauge if I should change the topic now to finally get to what I need to say/show her, or if I should wait tillt he next week. I also use it to gauge how deeply I can get into a subject before time is up. My last T did not have a clock in the office, and we almost always ran over-time. It never bothered me, unless we were on a really uncomfortable topic and I wanted to be able to bolt from his office. I always have my phone with me, so I can check the time as needed.
