"ball"
"okay, here's a ball"
"Noooooooowoowoowowowoowowowooooooo" *sob*
"no ball? fine. the ball is here if you want it"
"noooooooooooooooooooo ball kitty* ball nooooo MOMMY!!!"
Attempt to hug, get shoved.
"yes, there is a kitty, do you want to pet the kitty?"
*sob* *sniffle* *face twisted up in that heart wrenching way that means the end of their baby universe has come* "noooooo baaaaaalllll"
*hoping to get a clue as to what on earth is the problem*"okay, here's a ball"

"ball!"
*Kitty, by the way, is said in a perfectly calm voice and is simply a note of observation that one of our cats is in the room.
