when you knock on my door, i will welcome you with open arms; my long lost friend, my dearest enemy, my unwritten play in three acts. my forgotten peace of mind, the one i never learned to hate, the one i'll always yearn for; my oldest regret, my most recent mistake. when you knock on my door, i will let you in, but won't let you stay; the one i never asked for, the one who always walks away.
