Everyone is put into your life for a reason. Some are there to teach you lessons, some are there to love you, some are there to teach you what its like to be left, and some are there to show you what it means to be happy. I think the hardest thing to realize about people, is that unfortunately people leave. Not everyone will leave you on purpose or forget about you, but separating, drifting, and growing up are all parts of life. And I know sometimes that may seem unfair or cruel, but in reality it teaches you a lot. It teaches you the value of time. You never know how much time someone will spend in your life, so you need to cherish every second of it.
