I really like Rachel's personality and how she reacts to what everybody does.
Just from that story I can tell so much about your character. Rachel is the perfect example of a little girl growing up and learning all about changes and special events that can happen in a life time. I love the way you discribed the sadness and anger of not being able to go swimming in the water. You discribed it so well!
Write something about yourself. No need to be fancy, just an overview.
