A rotating, soundless object followed me home from boy scouts.

I am unsure of the exact date but I know that it was my fourth grade year of school in the spring.  I was walking home from Boy Scouts on a monday night when I saw an object above me.  It was about fifty feet over the tree tops.  For about three blocks the object was slightly  behind me.  As I turned right onto my street the object did not follow any longer.  No one except for me was on the street.  I then ran into my house.
 Watching TV in my sun room I saw it again outside of the windows.  Then later, I went upstairs to my room to go to sleep.  I felt that something was outside so I pulled back my curtins.  The same object as before was about fifty feet above my neighbor's house across the street.  I then remember going to sleep.
 The next day at school I asked the class if they had seen anything weird the night before. A couple of people said that they had seen a strange object.  These classmates were from my eastside neighborhood.
Date is approximate.  PD
