Persuasion

Is it just me, or does this kid look like he is trying to talk me into something?

We start with the offhand comment...

Explain that it is the most reasonable request in the world...

Emphatically point out every other kid that gets what you want...

and end with a pleeeeeeeeeasssssse!

And yet, I still have to say no.  Sorry kid.  No motorcycles today.
