walking home i saw a gray saucer in the sky!!!!!!

i was twelve years old. i was coming home from school which was down my street.  i looked up at my neighbors house and between the roof and the tree i saw a gray saucer. i remember it like it was yesterday.  it had a dome top and dome bottom and completely gray.  i stood there for what seemed like eternity and watched it pass from the branch to the back of the house.  after it passed, i ran inside to grap a camera, and my mom said where have you been?  i told her i was outside and she said she had been calling my name for half an hour, but i never heard her.  it was complete silence.  after 18 years, i still can remember the cars on the street, the colors of the houses, and the sounds of the neighborhood.  i never told anyone till now because my sister was military intelligence in the army.  but sitting here at the age of 30 i know what i saw!
Witness indicates that the date of the sighting is approximate.  PD
