I guess they don't owe us an explanation really, but it seems weird that yours wouldn't even tell you something general. I certainly wouldn't want any descriptions of explosive diarrhea or anything like that, but saying that he had to cancel because he was sick seems reasonable.

I think mine have always told me without me asking. I guess I did ask my therapist if he was going somewhere fun when he said he'd be out of town next week. I'm not sure I really cared all that much. I was sort of asking just to be polite and it seems the thing you do. He told me where he was going.

Frankly I think they might as well just tell us. Otherwise who knows what we will imagine. Similar to I told my coworkers I was seeing a therapist because I have to leave early...and if I said "doctor" they'd think something worse was wrong. Why make them worry?
