You shouldn't ride your bike today.
You lost your helmet yesterday.
You could hurt yourself in a fall,
and then never ride at all.
Meg shouldn't always stay up late.
She knows her school bus comes at eight.
She'll enjoy herself late tonight,
but tomorrow she won't feel right.
They shouldn't stay in the sun all day.
Sunglasses and hats make it safe to play.
If they burn themselves in the sun,
later they won't have fun.
Al shouldn't run so fast, you know.
The sidewalk's full of ice and snow.
He could fall and slip and slide,
and end up right on his backside !
