Mine starts within a minute or two of start time generally. He does 50-minute slots, but is OK with going slightly beyond that at times, like up to 5 minutes. I generally keep track of the time and will say, "OK, I know we need to stop in a minute." Though sometimes then I keep going a bit, and he tends to let me. I think there have only been a couple occasions where he's finally said, "We do need to stop."


Ex-marriage counselor usually got us late--up to a half-hour late sometimes, usually more like 15 minutes. Sessions were technically 45-50 minutes, but he'd often keep us for an hour or more, sometimes more like an hour and 15 minutes. It was difficult at times, if he kept us long one session, then had us leave on time the next. As much as I liked having longer sessions at times, I think I generally prefer my T's approach of consistency (certainly the starting on time part!).
