"You," Peter said, as Nathan's Mario plunged into a bottomless pit, "are really bad at this."
"That's because I have a life," Nathan said.
Peter stuck his tongue out. "Doesn't mean you don't suck."
"Hey, language." Nathan handed the controller back to Peter and watched him navigate Luigi over pits and under blocks and through pipes.
"You say 'suck' all the time," Peter pointed out as he picked off a row of goombas.
"That's because I... suck," Nathan said. "You're better than me."
"Better at Nintendo," Peter said, as his Luigi conquered the level.
"Way better at Nintendo," Nathan agreed.
