Chances

How can you ask for a single chance?
You've had your shot, twice...thrice;
I see a thousand when I take a glance.
Only one? Wouldn't that be nice.

You're only asking for ONE more.
Easy enough wouldn't you say?
It's a lot more difficult after a score
One more spent and another to pay

How many chances do you need my friend?
Your requests, I fear, will never end
The points against you begin to mount
I'm sorry the pretenses never count!
