So, last night I had another lesson- this was instead of the Thursday lesson, because I had book club.  I rode Solie.   We even did some no hands (and no lunge line) work up in the round pen.  The bareback lesson apparently had quite an effect- I felt much more confident, and according to Heather, looked more confident as well.  The best exchange of the night follows.  (Well, some explanation first.  I've been having a problem wherein instead of keeping my weight centered over the saddle, I am shifting it to the right.  The conversation occurred at the sitting trot.)

H:  Are you thinking about your weight?
WG:  No, I'm thinking about how this is totally the wrong bra for this.
H:  That is definitely not what I expected you to say.
