It's often said "If you love something, let it go. If it comes back, it was meant to be." When you lose someone, sometimes they will find their way back to you. They'll find their way back into your life because maybe they have something else to teach you. Maybe they'll come back into your life at a time where they felt you need them the most. When they do, though, you will both no longer be the same people you once were. You won't understand each other in the same way. But, if they do find their way back, allow yourself to understand how beautiful your new bond with them could be and the new memories that can be made.
