"I'm right, I can't be wrong, I can't be wrong..."

Sheldon stared at his whiteboard, muttering, checking himself over and over again, and finally turned around and shouted at Mary, "I'm right!"

Leonard gasped.

This is really heartbreaking.

He was worried that Sheldon could not bear it.

"Do you feel familiar? Now you can feel how we feel when facing you?"

Howard teased.

He doesn't care whether Sheldon can bear it or not.

He only knew that when she was facing Sheldon, she felt like Sheldon was facing Little Mary now.

The more unhappy he was in the past, the more pleasant he is now!

"Ahem, Mary, be polite."

Adam coughed lightly: "Uncle Sheldon is my good friend and your mother. He was indeed very smart when he was a child."

"Oh, I get it."

Little Marie nodded.

It may not be good if you are young.

This principle is too simple.

Little Mary comforted: "It's not your fault. It's all because the United States does not use international metric units. Many Americans are prone to making mistakes in international metric units."

"I was 10,000 times wrong..."
