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