Dependence

I have a friend who comes along, Perhaps he is an enemy, I hear him knocking at my door, When boredom strikes or shadows creep The sound he makes is so alluring, I often wish he’d go away, And yet I always let him in, Or is it he who’s letting me? He speaks in lies that taste like truth— In whispered words that mask the pain, Yet never satisfies the thirst, But slowly poisons over time Our friendship started years ago, And seemed back then a two-way street, But now I know the more I take, The more he takes from me
