When I eat a pizza for dinner, the first thing I do is smell the dough, the toppings, and the delicious cheese. I look at the pizza, and see the grease dripping from the edges of the dough. I examine the toppings, making sure that no undesirable toppings are on my pizza. I can smell the cheese and the toppings, and my mouth waters at the scent. I pick up the pizza by the crust, grease making my hands oily. I bite into it, the cheese warming the roof of my mouth. The cheese, toppings, sauce, and dough are being chewed in my mouth, and they turn into a symphony of flavor. I swallow, and I take another bite, and another, until I finish the pizza.
