I remember one time a few years ago when I had the opportunity to eat pizza as much as I wanted... and I followed through. For about three weeks, I ate nothing but pizza and the complementary breadsticks, sometimes ordering out, sometimes using digiorno's and even making my own at one point. But toward the end of the third week I had pulled a pizza out of the oven too eagerly and, in the end, ended up eating an UNDERCOOKED pizza.
I made up my mind after that that I would never eat pizza again and I was thoroughly sick of it.
Now that many years have passed I have recovered from my aversion and have a (healthy) relationship with pizza.
So the lesson is; do not undercook pizzas. It can ruin something great in your life ;_;
