I want out!
I don't know why.
I just do.
That's reason enough!
Perhaps you need a reason.
I don't. I'm a dog. That's reason enough!
It's not important that you know.
I do. That's reason enough!
So, let me out, right now!
If you need to wait in the cold until I'm done,
So be it.
I don't care that it's cold.
I'll let you know when I'm ready to come in.
When I'm ready, I'll let you know with a quick bark.
I have important things to do!
I smell something I need to check out.
I see something I need to investigate.
I can't help it if you don't see it or smell it-
It's important! I got'ta check it out!
Just relax. I'll give you a bark when I want in!

OK, I want in.
