Since we had to have sessions over the phone or Skype, T has always been 1 or 2 minutes late.

She usually initiates the call. She always ends the session dead on time so I don't think it is a problem with her clock.

When we were having face to face sessions I always made an effort to show up on time. I know one or two minutes is not that big of a deal but still, being late is being late.
