Sometimes, I truly miss those days at the park, around sunset when my parents would call out to me. I've grown bigger but I haven't changed, and this was something I was going to write for myself but I didn't like how it felt as if I was hiding myself, and this might just be my rebellious side wanting to do things they tell you not to do, but somewhere along the way I've grown tired of this place where I only post pictures. It's not in my nature, and maybe because I received a lot of love today, but there are so many people I miss and want to see he."
