That’s quite a compliment!
When I was teaching in Taiwan, one sixth grade class gave nicknames to all of their teachers.
One of the teachers had a full beard that was light colored and they called him Santa.
Another was teacher was called “Look” because he was always looking out the window.
They called me “Teacher K” because I always say OK” while I’m teaching.
It’s not a particularly “good nickname,” but one of my best friends goes by Ron, even though his name is actually Herbert. What’s puzzling is that he has no idea why he is a Ron. There’s no “Ron” or “Ronald” in his name or in the name of any of his family members. His family called him that from a very early age and he can’t remember a time that he wasn’t Ron. His father just told him, “We started calling you Ron as a baby.” No further explanation.
Yes, I remember hearing it quite often. I could never figure out why my dad decided to call me a version of that. Maybe because it was a funny-sounding word.
I miss my dad.
