Lexi-isms

I have been fighting a really bad, nasty headache since Sunday that finally left me. But, this morning I have had a tummy ache, probably from all the meds I took trying to rid of the headache. Lex asked how I was feeling this morning I told her "my headache is gone, but now my tummy is upset". She said "oh, mom, I know what's wrong." I said "Oh you do?" She said, "well, if your head hurt and now your tummy aches, and it hurts to chew, that means you probably have the flu." I told her thanks and took her to school. Since when does your mouth hurt to have the flu? I thought that was funny.
