"The fuck you want me to do? Go and ask the chicken?" Ein muttered.
A wave of snickers rippled through the crowd of kids.
Luke's grin didn't waver, but his eyebrows shot up in mock surprise, milking the crowd's laughter.
"Careful, Einstein might throw his apple at you and discover gravity," someone joked loudly.
Ein rolled his eyes and looked back at his lunch. "That's why you're failing physics. Idiot."
The kid wasn't happy about it. He slammed his spoon on the table and jumped up. "Hey! I didn't even say anything wrong!"
"Isaac Newton invented gravity, not Einstein," Ein retorted, not bothering to look up.
Luke chuckled awkwardly and patted the kid who was wrong, trying to dissipate the tension before it went too far.
Another student joined in to ease things. "Just ignore him. That Einstein is always looking for a fight anyway."
