I agree with other posters that it's reasonable to ask for anything, but it's also reasonable for the T to say no. One thing that I personally wouldn't feel comfortable asking because I feel like it would be too much, is that my T learns about something new just for me. While I still think this is a reasonable thing to request, I don't feel comfortable doing it myself. I just feel like it's too much to ask of my T. She already does so much for me, so for me to ask her to do more just feels like I'd be asking for too much.
