Intense 10 year old

I was out in my neighborhood going down the hills on my long board just chilling and a girl who was out rollerblading who I had never met before came up to me and started talking. Talking is an understatement- I don't even think she took a single breath during our 20 minute encounter. She proceeded to tell me everything about her life and ambitions and how her Mom looks 20 even though she is 40 because she gets surgery all the time and always dyes her hair. Then she said that her sister got pregnant and has to move out. I asked how old her sister was and she said..."oh about as old as you 16-17" I told her that I was 23 and she gave me a look like why is a 23 year old going around the neighborhood on a long board don't you have a life or a car? I asked her where she lives and she said she would show me if I was allowed to go past the mail box...I told her I could. I went home and was telling this story to my Mom and brother and it turns out they know this girl and her family and the things she was telling me are very big secrets. I feel bad for that family because either they have a pathalogical lier in thier family or just a big mouth...don't ask me which is worse.
