An off day

Traveling really sucks it out of everyone, especially little people. So couple that with the traditional two-year-old indecision and this is what you get.

Me: "Why aren't you eating your pizza?"
Davis: "Me no like mushroom."
Me: "Ok here you go," sans mushrooms.
Davis: "No like meat," in whiniest baby voice you can imagine. And we all know this last statement is not true.
Me: "Here you have this piece with just cheese."
Davis "Noooooooo" waving his hands at the food in frustration.
Me "Ok, well then Aspen you can have this." At this point it was barely looking like pizza so I'd rather pass myself.

But apparently now that the dog gets it, it's worth something to my overly tired son and he melts down to only be salvaged by me offering him the whole pizza, to which he of course..... turns down.

What did I miss?!
