back in 1993 i was giving private computer lessons to bobby kopp of bethesda, maryland, who was around 4th grade at that time. when some other kids stopped by to visit, i introduced bobby as a person introduced in computers and astronomy.
bobby quickly corrected me in a nice way. "phil, i'm not interested in astronomy. i'm interested in astrophysics."
oops, my mistake.
bobby, if you happen to be reading this, i'd love to hear from you to find out what you're up to these days. yup, i know you go by the name robert these days, but i'll always know you as bobby. you were my favorite student back then -- and you remain dear to my heart. i sure hope you continued with the great pranks we did back then.
