They dont care.

       You never know what someone really means by what they say or do. They could hold your hand, and never plan on talking to you again. They could invite you over, just to say silently goodbye. I simple 'see you later' could mean you'll never talk again, but goodbye is too hard.
       You don't know who really cares, who doesn't care at all, and yet, we feel the need to impress everyone we think could have the slightest interest in us. Anyone who so much as gives you a happy smile. Anyone who spends the slightest amount of time with you. So you change. You change into something you're not and something that he may or may not want. And you lose yourself, you no longer remember who you were, or wanted to be. All because of someone who isn't going to be in your life for long. Now you're left alone, and you dont know who you are.
