I’m practicing a word I’ve never used as I get on my borrowed bicycle for the last time and head out the driveway into the night. Practicing in my head as I leave the bicycle in front of the lab building and go up to the third floor one last time. Practicing behind tight lips as I turn the handle of the door. And when I step through and see them all there, I know I haven’t practiced enough.
The most difficult word to say in any language is goodbye.
