If you meet your best enemy on an lonely place.........

Hmm, interesting question...I'd probably keep away for a few hours or so & try to think on why he is my best (or is it worst?) enemy...because believe me, I can definitely live in silence & be by myself especially if it's on an island...then maybe I can then try to converse with him (if he's reasonable!) & try to sort things out--if things don't pan out--fine by me...sorry for him! live & let live!
