It seems SO weird that some T's actually have their phones on ring or even vibrate while in a session (I'm assuming most you are talking about cell phones), even weirder that some have the nerve to answer ringing phones!! My T always has her's on silent, and never looks at it. There have been a few times when she forgot to turn it on silent and it has rung during a session... she always apologizes, turns it on silent, and definitely doesn't answer it! I can see there being some extenuating circumstances where a T will need to answer a phone-- but in those (rare) cases I'd hope he/she would let you know that might be happening beforehand and assure you it's for a very good reason.

I did see a T briefly in a hospital setting once who had a horrible habit of checking the time on her cell phone like every 5 minutes during sessions. It was so distracting. I never understood why she didn't have a clock in her office. I remember thinking it would be funny to buy her a clock on my last session and be like "for the love of god, put this up!"
