A.M. P.M.

Conversations with my girl are always interesting.  Out of the blue, the door to her room opens and she joins the family convergence in my room.

Chi [smiling with new found knowledge]: I know what a.m. and p.m. mean. 

Mommy: Really?


Chi:     Umm-hmm. A.M. is at morning and P.M. is past morning.


Mommy: Where'd you get that from?

Chi:    My head. [then, thinking I didn't believe her source, she adds] What?  I'm smart.  Even Mr. Moore and Mrs. Sloan [her substitute and her teacher] don't know that.
