I met Darlene at the Lawrence Hall of Science in Berkeley. She was a graduate student completing her doctoral degree, and I was a newly minted Ph.D. doing postdoctoral research. We were randomly assigned to be office mates in a wing of the Hall filled with researchers studying math and science learning. I will always remember how Darlene was in those days. I thought she was very classy, with her glass coffee mug and brown hair up in a bun. She looked poised and professional, but her sense of humor soon infected me, and we laughed together about the goings-on of the academic and personal world as we became friends. Later on, we both had similar paths: we left the purely academic world and made our ways earning a living in the computer industry. I knew Darlene for over thirty years, and I never got to spend as much time with her as I would have liked. Now, I have only my precious memories of lively, laughing time spent together.
