गुरु गोविंद दोऊ खड़े, काके लागूं पाय, बलिहारी गुरु आपने गोविंद दियो बताय। — Sant Kabir

Every diagram you drew on that dusty blackboard is still clearer in my memory than any slide deck since.

Not all heroes wear capes — some carry a duster and a stack of ungraded notebooks.

Sir, remember the kid who never raised a hand? I still hear your voice when I'm stuck.

If patience were a subject, you'd have taught it best without ever assigning homework on it.
