Rival in the future?

Penny decided not to talk to Ray and completely treated him as non-existent. A person who wouldn't mind risking his reputation for a petty reason was not worth the death of her brain cells. 

"Penny, I didn't mean to hurt your feelings," Ray apologized half-heartedly, but she chose to enjoy her last snacks and ignored him. "You said you only have five of those, but that's the fifth one. If I count the one you gave me, that's six. I'm still hungry."

Still no answer.

Ray eventually gave up. He didn't know what came to him and spouted such lines. But he knew he didn't want to offend her that way. 

For a good five minutes, silence enveloped the old and dusty classroom. Penny didn't even give him a glance throughout while Ray ended up staring at her.
