: I'm curios

I dont understand how you can smile all day long but cry yourself to sleep at night. How pictures never changes but the people in them do. How your bestfriend can become your worst enemy or how strange it is when your worst enemy turns into your bestfriend. How forever turns into a few short months that you'd do almost anything to get back. How you can let go of something you once said couldn't live without. How even though you know something is best for you, it just hurt the same. How the people who once wanted to spend  every second with you, think a few minutes of their time is too much to spare. How people make promises despite knowing how common  it is for promises to be broken. How people can erase you from their lives just because its easier than working things out.
