Sibling Rivalry

Get off it! It's mine, not yours!
It's your turn to do those chores
Mum said I could sit there, not
You and Dad said you've got
Work to do
Mum! It's not fair! She always gets
The best clothes and TV!
I've got to get my football
Kit washed, you see
So I can't polish the car today
And I haven't time to give the
Guinea-pigs more hay!
Get her to do it!
Sorry, I know for speaking to you
Like that I nearly blew it
But just look at her with that
Perfume!
Mum! Dad!
Ask her, not me, to dust the room!
