Well I lied to her!

Last night ...
Me: Mason, you can't play anymore video games until you can count to 100.
Mason (with much annoyance in his voice): Ohh-kay.

This morning ...
Mason: Mommy! I learned how to count to 100 last night!
Me (with much exaggeration in my voice): You did?! That is great!
Mason: So now can I play video games?
Me: *sigh*

This afternoon, after practicing his counting ...
Me: Okay, now start from one.
Mason: Mommy, I can't count to 100!
Kyle: You told Mommy this morning that you could.
Mason: Well I lied to her! I couldn't take it anymore! I wanted to play video games!
