"When you're used to getting just a piece of bread for a meal, you don't realize that you can ask for a plate of pasta. You have never seen a plate of pasta. You don't even know it exists. So, to ask for it is totally out of your reality. Hopefully, at some point, either someone shows you a plate of pasta, you read about it, or you hear about it enough so that it becomes real, and it's not just a fantasy anymore, and then you start thinking "Hey, I want that pasta.""
