Country Music Word Problem

In the Patty Loveless song "You Can Feel Bad If It Makes You Feel Better" the singer states:

Maybe I'll go out tonight, yeah, I'll paint the town
And maybe I'll run into you, while I'm runnin' 'round
There's a good chance I'll be alone
An even better one that you won't

Given the preceding, what are the odds that a) both will be alone and b) both will be accompanied. Please express your answer in terms of "chance" and show your work for full credit.


Extra Credit Question: The singer also states "Take another look at these tears I'm crying/They're not fallin' on your shoulders, they're fallin' on mine." Describe two situations, assuming normal human anatomy, in which a person could reasonably be expected to be crying on her own shoulders.
