I think that at some point I will feel comfortable asking him, but not yet. I would guess that someone who would join a random study group with a bunch of people he just met has to have some level of comfort with himself, because I think that's the kind of thing that would make *most* people nervous, stutter or not. I was definitely a little nervous about it myself! And efficiency for the group didn't even cross my mind, I really just want to make sure he feels comfortable and welcome :) I felt a little extra responsibility last night I suppose since I hosted the group at my home.
