I wouldn't have a big problem with my T making a *short* call at the beginning of our session.

But if he interrupted the session to MAKE a call(not to receive one), I'd be offended. His phone vibrates sometimes during my time and I always notice and ask "do you want to take it?". He declines and we continue the chit chat. I wouldn't mind him answering it, as long as he keeps it short.

I have answered my phone 2-3 times in the past 4 years though. Does this make me a horrible client?
