Shut Up

"Shut up."
A contradictory message.
Home I'm told to shut up.
School I'm told to speak up.
Church I was told to speak up,
But now I'm told to shut up.

I never seem to know
When the time is right
To speak
Or be quiet.
When the teacher is talking,
My lips are sealed.
When other people are speaking,
What do I do?

Interrupt,
I'm rude.
Don't interrupt,
And I'm not heard.
