People never leave you. They might physically leave you, but every time you meet someone new, they leave a part of them inside of you, just as you leave a part of you inside of them. They add up to who you are, with personality and with memories. And they pulse inside you when you miss them as hard as your heart does when it beats. Their physical absence leave a metaphorical hole inside of you, because when they’re not around you, they don’t fill you up as they used to. Nostalgia. Nostalgia.
