Mummy: "It's time to leave the park now DS/DD, I did say 20 minutes and you've had 25, and we have to go to Tesco on the way home to buy yummy food for dinner, so please get in the buggy, you can see Millie/Billy tomorrow, say bye bye now etc etc ......."
DS/DD: "Waaaaaaaaa waaaaaaaa waaaaaaaa while rolling on the ground or doing that running on the spot thing
Mummy, in weird uber-controlled voice: I understand you're tired and playing in the park is lots of fun but we do want lovely dinner don't we, so please get in the buggy etc etc on and on..........
DS/DD: Waaaaaa waaaaaa waaaaaaa
I see it all the time, it's hilarious. I'm all for talking properly to children and explaining things etc, but seriously when they're in that state it won't go in! Just pick them up, quick cuddle, plonk them in the buggy and go!
