OH my gosh.... my DD does this when she is READING! It is so annoying! I am CONSTANTLY telling her to SLOOOWWWWW DOWN! Her teachers at school tell her that too. She's not as bad when she talks (though she NEVER STOPS TALKING) but man, I can't get her to slow down with her reading. When she is talking it's just NON-STOP! I swear, the kid even talks in her sleep!!!!
