"No again"
Squishy frowned when he heard shouting from the twin's room. They were discussing again.
"Why do we always argue?" Don asked as he walked into the living room with a cup of coffee.
"I don't know!" Squishy exclaimed, "But they can't continue fighting among themselves all the time"
"Its natural" Art said while smiling, "They are totally opposite"

"You're immature!"
"And you're stupid!"
"You're unbearable!"
"And you think you're not!?"

"Like the Yin and Yang" Art said.
"Yin and Yang?"
"Yes!"
"But, the yin and yang represent the women and the men" Don sat on the sofa, watching his two frat brothers.
"Not necessarily" Art smiled, "Represent the opposite natures, like the day and night"

"You're a party pooper!"
"And you are very irritating!"
"Agh! I detest you!"
"I hate you!"

Squishy was about to speak, but Art continued with his speech.

"They complement each other, and one couldn't exist without the other. However, it is represented as its symbol, everyone has a little of the other inside"

Don and Squishy observed incredulous at such knowledge, when a footsteps coming down the stairs caught their attention. Terri and Terry, avoiding the glances each other, went down to the living room.
"Sorry, guys" Terry said, "I know you do not like it when I fight with Terri"
"Yes… I'm sorry" Terri looked at his twin, "But I can't bear to share body with this nerd!"
"Look who's talking, ballerina!"
"What did you say!?"
"BALLERINA!"
"Ok… you're dead!"

In this moment, Terri grabbed with his both hands the neck of his brother and began to strangle him. Terry lost his breath and fell to the ground with to Terri. The older brother tried to free the hands of his brother while Terri hanged his twin's neck with all his force.
"Apologize now!"
"N-ne-ver"

The Oozmas watched with horror the scene, totally paralyzed. Then, Terry hit the face of his brother to let him breathe. Terri back, removing his hands from the neck of his brother and rubbing his face with them.
"You hit me!? How could you do this!?"
"You tried to drown me!"
"You called me ballerina!"
"You called me nerd!"
"SHUT UP!". Both twins turned to find a very annoying Squishy, "Stop, please!"
"Yes!" Art exclaimed, "You shouldn't argue. You are the Yin and Yang"
"What?" Terri asked.
"You are the two opposites that complement…"
"…and could not live without the other" supplemented Don.

Both twins were seen together. Terri smiled at his older brother and snuggled into his neck. Terry, surprised at the act of loving of his little brother, gave him a little hug.
"They are right, Terry"
"I know…"
"Oh, Terry! I'm so sorry!"
"I'm sorry too, brother"
"I love you!"
"I love you too, Terri" the older brother smiled, "You're my Yin"
"And you're my Yang!"
