He knows his “May-nas”

In the car, riding home from Walmart, handing a Wheat Thin back to Porter.

Me:  What do you say Porter?

Porter: "Tu Tu" (aka Thank You)

Me:  That was nice Porter.  You used your manners.  You are such a good boy always using your manners, aren’t you? 

Porter: "May-nas"

I hand Porter another Wheat Thin

Porter:  "Tu Tu May-nas.  Tu Tu May-nas"
