Did you ever get into fights during your wilder days?

Yes, tons of them. 

But you smarten up and realize that you might come up against someone who has skills that could really damage you. 

It’s like Bob [in The Drop]. I imagined him as someone who would sit back, let everybody think he’s a nobody, and then he shows you that he’s the kind of guy you should never pick a fight with.
