At ten I went camping with my parents friends they had invited another guy with his son hi was thirteen to note at ten I looked like I was round thirteen either way I sorta fell for him he took me fishing, swimming, and we talked and had lots of fun his dad came up to me alot during the trip or at the campfire and would tease him about falling in love with me my parents did the same I missed him the second we left the camp. That was the most memorable days in my life! I herd he lives two houses down from my friend and I catch a glimps of him every so often I'm 13 now and he's ffteen or sixteen and I want to say hi to him but I'm scared he won't remember me or Something For some odd reason I still have a part of my heart that belongs to him what should I do? His name Is dustin or he also goes by Justin I don't know his last name so ya help?
