I'm going to bow out of this conversation. I appreciate your example of how you use leftovers (and how your example is similar to how I manage food in my own home), but this thread has gone from "I sympathize with people who avoid leftovers" to "I don't get bad vibes from a guest not wanting to eat leftovers" to "Is it ethically wrong to cook ahead?"

I'm sorry that the thread ended this way and for the offense that I have given. At least we can both agree that the letter writer is a dick.
