I don't believe in BFF (Best Friend Forever). I am saying this not because I depreciate my friendships with my friends. It is right the opposite.
I appreciate friendship more than anything that I won't think it's something that will last eternally so that I will value it now.
Let's not think about friendship for a lifetime. Think about friendship now. Think about how much we valued our friends today.
I believe if we appreciate each other well enough today, we need not worry about "friendship for a lifetime".
Nobody knows what is going to happen tomorrow.
