IMO, good Ts give homework. My last one (who I loved to pieces) always gave me a question or issue to think about and reflect on between weekly sessions. I would write about it and email it to him and then we had an immediate starting point for the next session, without having to sit around saying "well, what should we talk about?" which used to happen to me with regularity with a different T.

I liked it, myself, but everybody is different. I do think it's a valid thing for T to do, though. My current one doesn't do it and I miss it.
