It's crazy how fast people can drift apart despite the promises of staying together.
What's even crazier though is that you know all these things about them that you're just stuck with until you're able to let them go; their secrets and quirks and the way their eyes sparkle as you surprise them with gifts and love.
It's those things that make it so much harder to walk past them and act as if you haven't seen intimate parts of them. You make awkward eye contact that lasts less than a second and mumble a "Hey" before continuing on your way. As if they're just some old acquaintance, even though at some point you were each other's world.
