You were listening to your smartass best friend, Sahil, explain the lesson to you since you didn't pay attention in class, because you were daydreaming.

"Did you understand?" He asked , and you just nodded, and smiled sheepishly.

"You didn't..See." He explained again. He wasn't impatient or disappointed with you, he was calm, and wise. You called him 'Saint Sahil' to tease him sometimes. And he wears glasses, and is kinda a nerd.
