Brad was a hot teenager who went by "David" now, and David was a fat ten-year-old forced to go by "Brad".
"What's wrong, little bro?" Brad chuckled.
"Brad, I'm so short and fat. This is so unfair." Tears welled up in David's eyes.
"Hey, you just need to get out and exercise a little more. Stop eating so much candy. You'll get big and strong like me." Brad flexed his strong arms, the arms that used to belong to David.
"I'll never be as big as you," David said, looking with envy at his brother's body. "Face it, I'm short, I'll always be short. You got lucky. I didn't. These are the genes I'm stuck with."
"What's it like being short? I guess I'll never know, I ended up so tall and hot."
"It's horrible. I'm as short as the girls in my class. All the guys just walk around being tall and confident, like they did everything right. They all call me ugly and gross. Only because my legs aren't quite as long as theirs. That's it! My whole life it ruined just because my legs aren't a tiny bit longer. It's so unfair!"
"Hey, it's more than that, right? Here, stand next to me." David stood next to Brad and they looked in the full length mirror together. David's humiliation was on full display.
"Yeah, see? It's not just your legs. You're right that your legs are really short, both above and below the knee. But look, your feet are small, too." David looked at his small, fat feet. "And your torso is much shorter. Your spine is short, like every one of your vertebrae is just a bit shorter. And your neck is short, too. Your head is a normal size, but it's sitting on top of a short body. Every part of your body is a short guy's body. It's not just your legs."
David looked himself over in horror, realizing Brad was completely right.
"Even if you could magically make your legs a few inches longer, it just wouldn't look right. You're a short guy, through and through." He smiled. "Hey, but you're only 10. You're still growing.Maybe you'll have a growth spurt, still. But all the other guys in your class are gonna have growth spurts, too. Most likely you'll grow a few more inches while the tall guys get way taller."
