Professor Cater was known for his strict rule: no candies for students, ever. “Knowledge is sweeter than sugar,” he’d grumble whenever asked for treats. One clever student, Alex, tried to trick him by presenting jellybeans as “experimental molecules.” Cater chuckled but didn’t budge, instead rewarding the class with a book of funny riddles and memories at the end of the term. The students realized they didn’t need candies to enjoy learning, but Alex still left one on his desk now and then, just in case.
