1 minute would not bother me but “you’re the only patient in 30 years who ____” would absolutely bother me.

I would probably feel shamed by that kind of framing. It would be a lot more productive and interesting if the therapist asked what that minute meant to you. Are you worried about the T? Do you feel slighted, as though making you wait means you’re unimportant? Are they easygoing about starting late but very strict about ending right on time? Or maybe T is very exacting in some other way and you feel the standard is being applied unfairly? Do you feel uncomfortable in their waiting room? Maybe it’s something else altogether or maybe you don’t know the reason.

Your feelings are your feelings whether they’re very common or very unique and they deserve your T’s kindness and attention.
