Okay so, hear me out:

Person 1 is super protective of Person 2 (who is their bestie) and Person 3 has a HUGE crush on Person 2 and Person 1 gets super jealous because 'wtf dude why aren't we talking much anymore how could you' and one day the three of them are at the grocery store and Person 1 and 3 are glaring at each other but Person 2 is oblivious and so when they get to the check-out lane Person 2 says "man I wish I could get some gum" and so Person 3 says "oh don't worry! I can buy you some!" but Person 1 ain't having any of that so they too put a pack of gum on the checkout lane and Person 3 puts yet another pack of gum on and this goes back and fourth for way too long and eventually there's no more gum or candy in the check out lane because they piled it all up on the checkout lane and Person 2 is kinda like 'k'
