Last night I went grocery shopping. I was going to make tacos for dinner, stock up on pizzas, get some more cereal, and get some soda for the party at work tomorrow.
Pizzas? 4. Check.
Soda? Dew and Coke. Check.
I bought everything I needed to make tacos EXCEPT meat.
So.. instead of tacos. I ate pizza. Rather, my roommate and I ate pizza. Ok, pizzas. There's one pizza left. You do the math.
