When former students return as hiring-committee members

Several times in recent weeks I enjoyed a (for me) new experience (but one that I know many other law-profs have had) -- former students (in these cases, students I taught during my first semester, in the Fall of 1999) were back on campus for on-campus interviews and meetings with current students.  I felt, well, (a) old ("Good Lord, was I teaching law in the 90s?"), (b) humble ("I cannot believe they let me teach law to this guy -- I didn't have a clue what I was doing.  Thank God it worked out for him!"), (c) proud ("Dang, this person seems happy in her vocation, and is thriving!  If I had anything to do with that . . . cool!"), and (d) grateful (both to the former students from coming by and re-connecting and to all those who made it possible for me to be in the position of helping with the students' education and formation).
