I get desperately lonely

Charlize is watching a movie in one room, on the other end of the house Cadence is asleep with her arms thrown over her head, and I am here in the middle, baby monitor pressed to my ear. You don't know it, but I wish you were here. My heart aches for the time when we used to talk long into the night, sharing secrets, comforting one another, teaching each other important life lessons. You're gone now. Part of life is moving on from things, from people, but I never thought you would move on from me. When I was a kid, I thought friendships were meant to last forever. When did I stop being a kid?
