<human>: Can you provide a brief overview of the text?

I am getting absolutely fed up with my sister. All she does is snitch on me to mom and dad, sibling are suppose to have each other's back and she keeps snitching on me and acting like a third parent. 

I can't even hang out with friends with out her texting me asking me where I am. If I want to go out when mom and dad are not home she gives a time I need to be back or most of the time does not let me go at all. 

I don't understand this attitude she has where she thinks she can boss me around and tell me when I can go out. 

What can I do to get her to lay off me
<bot>: My sister won't get off my case, she keeps telling what I can and can't do and I am sick of it
