Get on well with your sister!
Don't ever kick your sister.
Don't slap her on the chin.
Don't shout at her ''Silly!''
Don't do such an awful thing!
Don't put a ''Kick Me!'' poster
On your sister's back.
Don't take a little mouse.
Don't put it in her bag.
Don't take a plastic spider.
Don't put it on her head.
Don't leave your dirty trainers
Inside your sister's bed.
Don't do this to your sister
For if you ever do,
I'm sure she may also
Do something worse to you!
