How...

I don’t understand how can you smile all day long, but cry yourself to sleep at night. How pictures never change, but the people in them do. How you can love so innocently, but it can turn into anger so quickly. How your best friend can become your worst enemy. Or 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 letting go of something is best for you, it hurts just the same. How the people who once wanted to spend every second with you, think a few minutes of their time is too much time to spare. How people make promises, and bear their souls to someone despite knowing how common it is for promises to be broken. How people can erase you from their lives ‘cause it’s just easier then working things out.
