Opening Doors

I've got a pretty
Long hallway to walk down.
Three out of
Fifteen doors
Have already been
Opened.
And there have been
Good things behind them.

I'm opening a fourth
And I'm terrified.

I don't want my
Parents to be right about
This one.
But I don't know
What I'd do
If there were
Good things behind it.

We'll find out
Soon enough though.
