Calvin comes home from preschool regularly bragging that he tasted the snack that day even though it was something he didn't know about and his friend such-and-such wouldn't even try it. And I make a big deal and tell him I'm proud (which I am, and I do make him try everything at home). But then on pizza day the kids go to the pizza place and make their own pizzas and guess what Calvin puts on his pizza? Cheese. Picky friend #1 puts on green peppers and sausage and olives, and picky-plus-allergic friend puts on all the meats and onions, and Calvin who will try anything once puts on cheese. And it's actually pretty good.
