One fine morning, the Right paddle showed up to play against his opponent. He bid his time for an hour, trying to play by himself but ultimately got bored. "Left said he'd be here at 7" he muttered to himself before finally leaving.
That evening, Left paddle showed up to play his favorite game. He stretched, flipped up and down the screen and practiced a few serves while he waited, but eventually gave up and went home after saying "Right promised me he would be here at 7."
Lesson: Timing isn't everything, but it's kind of important.
