Mindsets require a great deal of evidence to reframe.  When we lack that evidence, we get stuck in incorrect thinking. Z humbled me with plenty of evidence to overturn my mindset about him.  He was impeccably professional, patient with difficult students, and as kind as he was brilliant. Students’ work, after he taught particular lessons, reflected that he was probably one of the best instructors I had ever worked with. He unconditionally covered for me when I took a day off to attend a funeral, and he took on twice his share of papers to grade. All without complaint and with good cheer.  In the process, Z unknowingly taught me lessons about unexpected connection, inspiration, brotherly love, loss, and ultimately, letting go.
