I liked it.
You could have maybe gone into a little more detail about the walk itself. Maybe gotten the lead into a little bit of mischief/trouble on the way. Made it a little longer, but hey, that is just me.
You have a tiny error here: "The 3 of us and her best friend Brittany had grew up ".
I think it should say "had grown up together".
About the car crash I`m reminded of a movie quote from a Kathy Bates character: "Face it Girls - we are older and we have more insurance".
