[Former student] came home for 10 days during Passover (the advantage of going to Brandeis--they get Jewish holidays off) and I mentioned that you'd said hello. She asked that I be sure to tell you how much she appreciated your kindness and your sincere interest in TEACHING. [Former student is] not innately mathematical, but was able to understand the concept somewhere between your third and fourth different approaches to teaching it; she points out that you respected your students and cared that they learned. May the pain of beating your head against the wall of imbecilic oversight be alleviated by the truth that at least many of your students are ready and willing to learn from you. Thank you for all your efforts.
Upon reading that this morning I decided that I should probably go home, because the day couldn't possibly get any better after reading that!
