One Hit Wonder

Our little Morgan has been full of one liners lately.  Recently she was talking to her cousin Amelia on the phone and part way through the conversation we heard her say "OK...let's move on."  During our vacation Mark was upset that the sun was not out and he couldn't work on his tan.  Morgan told him he was going to have to "deal with it."  Just tonight I was explaining that her two friends would be over until late in the night when the grown ups got home.  Like a half sleepover.  She said it was all OK and that she would "look after them."  She is 4 months older after all.  Of course our favorite that we hear all the time is "what the heck."  

Where does she come up with this stuff?!?!?
