Lin Wu and Shana crouched at the edge of the rooftop, with their hands propping up their chins, staring at the opposite side in quiet contemplation. They had completed the most difficult task of getting up to the roof, yet they hadn't anticipated getting stuck at an unexpected part of their plan.
Shana said, "You're one meter eighty tall, and with your arms stretched out you reach about two meters forty; deducting the head and neck, that's roughly two meters twenty. Therefore, theoretically speaking, if you were to stand at the edge, raise your arms, and fall forward, you could grab the floor of the opposite rooftop. From this, we can infer that you should be able to jump across."
Lin Wu looked at Shana, "Theoretically speaking, with a snowboard one can fly quite a distance, do you want to give it a try?"
"Oh, right," Shana's eyes lit up as she was reminded.
Lin Wu quickly said, "I was joking."
