I wrote out a favorite Hebrew verse on the blackboard. When my prof entered the class, he took a long, staring look at the blackboard, and his face soon showed his puzzlement. It dawned on me later that he had never been taught Hebrew cursive. My prof was a PhD and well-established Hebrew Scholar. But I might as well have written hieroglyphics up on the board. He couldn't for the life of him decipher my cursive Hebrew.
What's funny is that as a Jewish kid going to Hebrew School, you learn the alphabet in block letters in kindergarten. But shortly thereafter, you learn to write cursively and never again write Hebrew out in the block letters. I would have a very hard time today writing out Hebrew block letters, since the cursive system is so ingrained in me. (It's much faster to write too!)
