Here's a little conversation between my wife and 4-year-old son that I found recorded on a scrap of paper from the pocket of some shorts I wore during my recent vacation in the Minnesota wilderness:
D-: Can I have a burrito?
J-: ... You mean Doritos?? No.
D- (runs to the chip box and returns with a visual aid): I mean these!
J-: Those are Cheetos, and no, you can't have those right now.
D-: OK, I'll save them for later, then.
D-: ...And just hold them in my hand all day.
