I often get the question "What is a teacher?"
A teacher is "something that teaches something to something".
It can be a teacher teaching a student how to read or sit.
It can be a stone teaching you not to kick it because it will hurt if you do.
It can be nothing teaching nothing to nothing.
It can even be me teaching you what a teacher is.
The question is, did i teach you this or did you already know it?
May the force be with you
