You know what's annoying? One person thinking that they're superior to you, just because they caught something that you possibly overlooked.

I mean, let's say you're standing in a supermarket, shopping for that perfect cut of meat. You're standing there in the meat section, eyeing over the packs of pork chops, and you grab the one that just so happened to catch your eye. After you make your pick, someone else comes up behind you with the same agenda, and sees an even better package of chops. As they pick up the pork chops, they say, "Haha... Dude, you just totally passed up the best pack of chops ever. You're such a retard for doing so, too."

Maybe the first person though that their pick of meat was better than the second person's. Maybe the butcher came out and stocked the cooler right after the first person made their selection. Whatever the case may be, the choice the first person made was the appropriate choice at the time, and they did their best to find the most perfect slice.

This applies to life in so many ways, I can't even begin to label them. All I can say is that if you find yourself in the second person's shoes, think twice before opening your mouth. Better yet, maybe go offer the better selection to the first person.
