She can spell?

The girls and I were playing in the basement just before we left for the Yacht Club.  My Mom came down holding their bathing suits.  I said quietly "we should bring those in case they want to go in the p-o-o-l".  My Mom responded she didn`t think it was open.  Just as I was standing up, Zoe yelled out "But I want to go to the P-O-L".  I was so schocked I stopped dead in my tracks and said "what did you just say?".  She repeated her spelling.  Now how brilliant is that??
