an Opportunity Dilema

I didn’t rob a bank, oh no, or sprinkle on the DDT,

I just selected A to call

When B would do as well, that’s all,

But B was raw around the edges, don’t you see?. 

Now A has all the right relations,

A has tact in situations

 Needing tricky adaptations. 

I have certain expectations!

And I resent your accusations!

B would never do in certain semi-formal situations! 

Oh, but my B,

I left B over near the spring, B loves the sound of water so,

B cares for the country folks, you know,

You'll be all right, I said  You'll forget about me soon.
Yet, it's B I carry in my heart, humming the off-key tune,
