This conversation took place in our house today:-
Screams from both children upstairs.
I shoot up the stairs to be greeted by DD3 sobbing quietly and DD4 howling loudly.
DD4 demanded instant sympathy and uttered the immortal line "I hurt my finger so much when I punched my sister!"
Needless to say, she was told that it jolly well served her right and she should not have punched her sister, full stop.
DD3 then got sympathy.
Neither of them sustained any visible imjury and both were utterly painfree after about a minute....
Needless to say, after being separated and put in their respective bedrooms, five minutes later they inform me that they are best friends again now, so please can they play together in one of their rooms :-)
