Dear Brielle, Jasmena, Jordan, Karuna and Samadhi,
Now that you have successfully completed your last history outcome, I just wanted to let you know how proud I am of all of you.  Over the course of our studies together, you have been consistently interested, engaged, and keen to learn.  Your contributions to our discussions of historic events and issues were always to the point, intelligent and, more often than not, hilarious.  I know I'll never be able to get the image of the goldfish bowl out of my head.  :D
It is unfortunate that this last term we would have had together, we were deprived of so much of our class time, but being the glass-half-full kind of person that I am, I am grateful for the time we did get to share together, whether that was just this year or last year as well.  You guys have been a joy to me, and I will miss you.
