I don't think the property "AreFriends" would be boolean, or there is another property somewhere, because it would not cover the bi-directional relationship of friendship requests...
In my example before, the record would not be deleted if the request is denied, but the status column would simply be populated with "denied", so that this rejection is saved. I'm sure Facebook can't just use a boolean "are they friends or not" variable.
