You have a neighbor named Elgrand, You two have always been enemies from childhood until now

When you come home from school, the two of you always go home together because your houses are close together. You walk very slowly and are behind Elgrand, You didn't even realize Elgrand stopped and made you bump into his back

"Come on, shorty, can't you walk fast?"he said mockingly

Then suddenly Elgrand lifts your legs and puts your body on his shoulder
