Keegan:

Keegan did a "no no" and was corrected.  (For doing something I had just told him not to do.  Third time this week he's had short term memory that way.)

Anyway, I said, "Keegan you must obey mommy."

Keegan, with a wide eyed, innocent look and a voice filled with awe at this new revelation, "I didn't know that."

Kendra:

Then, I asked my sweet Kendra to help me remember the window measurements when we went curtain shopping, reminding her, "I need your young brain to help me." 

I love her reply, "Yes.  Mommy, your brain is so busy!"

I'm not forgetful, my brain is just busy.
