Why does Facebook have a not now button?

Like if someone requests you it says "confirm or not now" but then if you go to your requests it lists all the people you checked "not now" and says confirm or delete. Why doesn't Facebook just say "confirm or delete in the first place??"

Facebook is adding a new option to how people friend each other, trying to limit unwanted social behavior.

Now, when someone adds you as a friend, you can mark “Not Now,” thereby relegating their request to a separate menu called “Hidden Requests.” You can then confirm the person later in this menu, if you want, and in the meantime they’ll just see that they’re “awaiting friend confirmation” from you in the interface. Just as when you choose to not accept a friend request, they will not be notified when you give them this new designation.
