"Hmph! Are you boasting that you are taller than me now?!"
"I'm not—"
"Are you using your height to make up for your lack of intelligence?" Youyou sneered.
His brother was caught off guard by his words and hurriedly explained, "I'm not laughing at your short height. Don't misunderstand, please. Besides, I'm not stupid."
"You aren't stupid?" The younger twin snorted. "Tell me what the answer is to 1 + 2 + 3 + 4 + 5 + 6, then. Give me the answer in five seconds."
The older twin had no time protest and just quickly started counting with all the fingers in his fleshy hands. He looked dead serious as the time started to tick on.
"Time's up; what's the answer?"
"Is it 20?" His head spun from the effort of finding the total. He hated math.
"It's 21! Stupid!"
"Don't call me stupid…"
The older sibling pouted in resentment as his self-confidence was completely dashed!
