I received a very special card from my ex-student last November. It came when I was feeling worthless from months of futile scientific research. Chemicals bubbled, then fizzled. Experiments came and went. Failures lined up to greet me. Reprimands saturated the lab.
This card, it came right when I needed it.
It was a simple card, with checkered hues of grey, white and silver. It was a simple card expressing an expansive and overwhelming warmth.
"Lastly, I feel a very unusual sensation. If it is not indigestion, I think it must be gratitude."
I will remember this phrase for life. Thanks, Nelson, for being a great student.
