ATAT -- am sorry, that seems like a pretty solid goof-up for No. 2. I know this will suck all the more but I'd consider letting her know about the f-up (since she's been otherwise rather decently clued-in so far?)?

On cluelessness among Ts -- yeah, so leaving aside my former T (not exactly great in the clued-in department), I suspect the cluelessness is also (other than being aware of their own stuff) related partly to:
- what Ts consider crucial signs of distress (if you're not exhibiting those then all's well) and partly to,
- how clients have seemed in the past (so, if you've generally appeared 'together', any change in your emotional state may have to be somewhat significant for Ts to figure it out).
