When enough, is really enough.

And then I suddenly wonder how it feels to allow a stranger (no better than the previous ones) into your life so deep, you involuntarily gave him the possession of your soul, along with your heart.

And when he leaves, he'll return you everything including the remnants of your heart as a memorable souvenir. Everything is yours again. Till you realized...

Its your soul he keeps.

At least till as long as you allow him to.
