My patience is being put to the test today

Oh my goodness, it's only the afternoon and it's been such a long day!  Miss Thang has been so bad!  I don't know if she woke up on the wrong side of the bed or what, but I want my sweet girl back.  I'm about to outlaw the word "No" in our house, because it's being horribly abused by a certain 3 year old.  I'm really hoping she wakes up in a better mood after her nap!  She's feeling a lot better, but still gets tired pretty quickly and has a bad cough that's lingering.
