stop having my grandma be incharge of me

my family went away for one night and my grandma stayed here with me. she is bossing me around and i will not accpet it. she said i must go to bed at 11 o'clock because thats very late. im on april break and this is my vacation not yours so stop telling me what to do. if we get enough agreements with this petition we can bring light to this situation and have my parents come back.
