I'm not kidding

This morning, I asked my wife:"It's Wednesday, isn't it?"
"No, it is Thursday. You hear that? IT, IS, THURSDAY."
We looked at each other, and laughed.

This is a little secret between us.
Last Friday morning, my wife said to me:"Tomorrow is weekend, do you have any plan?"
"But it's Thursday, let's discuss it tomorrow." I said.
My wife smiled and said nothing.

And that night, I looked into calender by chance and found it WAS Friday, actually I'd made a mistake!
"Why didn't you correct me this morning?" I asked my wife.
"I'd thought you were just kidding."
"Oh my, have you ever remember me kidding on you?"

But the result was, I had to go office last Saturday to stop a running software.
I don't know why I always make such mistake these weeks, maybe a sign of I'm lost in my work.

Anyway, the Spring Festival is coming!
I'm not kidding.
