I don't understand how you can smile all day long but cry yourself to sleep at night. How pictures never change but people in them do. How your best friend can become your worst enemy, or how strange it is when your worst enemy turns into your best friend. 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 you couldn't live without. How even though you know something is best for you, it just hurts the same. How people can erase you from their lives just because it's easier than working things out.
