Competing With A Little Kid

"Stop moving!" Xin Zimen was annoyed by the person pacing before him for the past hour. "I'm getting a headache now!"

His elder brother stoped his back and forth parade to stare at his younger brother before he thought of something and went up to sit beside him. 

As he continued to stare intently at Xin Zimen's face, the latter was infuriated now, "What do you want?"

Xin Zemin straightened up when his brother paid him some attention, "Xiao Zi, why do you think Xiu invited us today?"

"I don't know and I don't care," was Xin Zimen's reply. "As long as she wants me here, I'll be here."

Xin Zemin rolled his eyes at his brother's reply, "Obviously, I'd also come whenever or wherever she needs me. But I'm just a little anxious. I don't know why. She sounded quite serious over the phone."
