Does Ramona Live Here?

Someone has stolen my sweet little 5-year-old and left Ramona in her place.  I swear it's true.  Mary has suddenly decided to love our cat to death.  I've caught her: "putting Jackie to bed" in a bin (holding Jackie down in the bin while trying to put the lid on); attempting to take her for a walk by buckling a belt around her belly; and just this morning, "making her pretty" by putting a necklace on her.  I think this is why we never had baby #5 - Mary would have loved him/her to death.  There's more . . . while driving to school this morning, we had a wolf sighting and I learned just today that no place is as great as Target because no other place has the red, cement balls by the front doors.  I didn't realize how awesome it is to leap onto the top of one of the those balls (or multiples if your Mom is being patient) and sit there looking pretty cool for mastering such a feat.  Ramona, uh, I mean Mary has also started telling me that she's not going to do her chores.  No emotion, just a calm statement of fact - "I'm not going to do that Mom."  To which I replied just as calmly, "Then you're not going to eat."  "I already ate - we just had breakfast."  "You won't get any lunch.  We all help out here and if you don't work, you don't eat."  "Tricked ya!"  Mary, aka Ramona, moves and talks constantly.  She just climbed onto my shoulders as if to prove my point as I'm typing this very entry.  She has a constant desire to invite over a friend, make up a dance, play a game, do a puzzle, go to the park, or read a book.  Anyone out there remember how long this stage lasts?  All I know is I'm very much looking forward to June when the other three yahoos are around to help me entertain her.
