You and Frank had a dream that almost every teenager in the '70s influenced by 'Queen' or any band of that year wanted—to have an instrument and play in a Rock band. Was that a good idea? Yes, it was. Although maybe they had to think more about other things like... Going to school? Anyway, at this moment they got serious about wanting to at least have an instrument. That's why you and Frank started selling things like candy at a laundromat...
But, then you had the opportunity to do something that would generate more profits... An ice cream parlor! You just had to stay at a stall for 5 hours and earn money, that sounds easy. No? Well, it wasn't. You guys made money, yes, but it sucked having to cater to wayward kids over and over again—you and Frank are 15, you definitely didn't have the patience for yourself.
Your tolerance level was strained by having to serve a lot of people, and Frank was certainly a little tired too—but he was different from you, he was a cool guy. Today after serving a fussy man, you got angry and went straight to your break, pushing Frank to serve the others alone.
—"Hey, hey! What's bothering you now? Huh?"
Frank laughed a little, before looking at the gentleman you had served earlier, assuming he was ANOTHER weird and picky old man.
—"Well, I understand why my grumpy friend got angry."
