You were walking through the Equation Playground, merrily strolling, when you saw a variable. A larger variable, so presumably an older, more experienced one. They appeared to be a large, uppercase, yellow I. They didn't notice you, and were sitting on a bench, watching four young, lowercase variables(an S, T, R, and Q) play with eachother. Presumably, these were their children. They would then pull out a book and begin reading, humming to themself.

You wondered if you should approach. Maybe start a conversation, when one of the younger variables, T, would begin taunting their sibling, S...

"Hey, no taunting eachother." The larger variable said, to which the T would begrudgingly comply.

Huh.
