I had never felt more....because of what happened this summer

I had never felt more grown-up, because of what happened this summer. This summer I had a life changing experience when in on night my life was about being a kid, to my life being about the start of adulthood. Over the summer my life changing experience was, during the end of July my half-sister hung out with horrible people and was caught doing things that you shouldn't do ever. However, sh is also is a mother of my 2 year old nephew and decided to be a completely horrible person and expose herself and her son to those horrible things. By doing so, she made life horrible and left the responsibility of taking care, and protecting her son to me, my parents, and my real sister. When writing this I found that it may not be what you were expecting, or think that is smart to write this, but you asked wanted to me this summer, so now you know.
