My T typically asks me to text or email her and let her know the outcome of whatever the event was. She also asks me about it fairly close to the beginning of the session, if I don't bring it up myself.

ETA: I appreciate my T asking me to let her know how things went. It shows me that she cares and that she's supporting me. Plus, sometimes, after something particularly difficult, I need the connection! I also appreciate that she allows me to choose how I let her know - I'd feel strange if she contacted me. I'm always grateful when she brings up something in a session, it shows me that she's paying attention and remembers what's important to me.
