I never said this to him the last time I saw him, because we were taking a final for our Topics in Biochemistry class. He always showed up for tests just before they started, because he studied right up until he took the test and he couldn't study productively in the classroom. On the day of the Biochem final, he showed up just before the test was scheduled to start, as usual. We initially were quite worried because Marie hadn't shown up yet, but then I remembered that she took her final early. I asked him a couple of questions about the material to pass the time and review a little, but we were both feeling good about the test. When the final finally arrived and we got the test, we started it without saying anything to each other. He was still working on his test when I finished, and I was exhausted and didn't want to disrupt the class, so I just left. I prefer to think of the turtle pond walk as our last good friend time.
