A Lifetime.

"Sometimes in life there really are bonds formed that can never be broken. Sometimes you really can find that one person who will stand by you no matter what. Maybe you'll find it in a spouse and celebrate it with your dream wedding, but there's also the chance that the one person you can count on for a lifetime, the one person who knows you sometimes better than you know yourself is the same person who's been standing beside you all along."
