A Guest Err Umm Pest!

The cat whacks intruders when they come to play, except the old guy when in he does stray. Pat makes me leave him be. But then this isn't about me. We did that yesterday. Now it is about others who stray.

Hello all!
Where are you?
Down the hall?
In the loo?

I'm here.
I'll shout it clear.
Never fear.
I'll remain near.

I wish I knew.
Where did you go?
It can't be true.
You think me a foe?

I'm your friend.
I'm the best.
That we must amend.
After all, I'm your guest.

Shouldn't you be here?
Where are you?
I know you're near.
I'm turning blue.

That means I'm mad.
I want to see you.
I just entered your pad.
Come into my view.

I may block some.
I may stand tall.
I may be a thin chum.
I may shrink before all.

But I'm here.
I'm here to see.
I'm always near.
Come out to greet me.

I'll sit here.
Here I'll sit.
I know you're near.
Don't give me a fit.

Oh, there you are.
Out shopping I see.
My grocery bill is on par.
Oh...is that for me?

Would that be a guest or a pest? We'd toss them in the sea at no one's behest. We just would. Have any such "guests" at your hood? We've known a few but we stay out of their view. Otherwise we may be in jail because we'd chuck them out the window without fail. Or they may go through and break the glass. Yeah, to such guests, I'm not a nice little rhyming ass.

Enjoy your winter, smash a printer.
