Spinning metallic object.

Please note the date is approximate.  i recall it being autumn as i was wearing my coat whilst in the playground.  i even remember it being my new mauve winter coat.
 It was lunch time which was between 12 and 1pm (so ive put 12.30 as a guestimate).  I was at primary school, first year aged 5, in the playground playing on the slide and remember hearing a low humming sound.  
I looked up and high in the air was a ball shaped metallic grey object spinning in the sky.  I don't remember if i said to other kids to look at the object so i dont know if anyone else saw it.
 i told my parents that evening at home and they laughed and put it down to "overactive kiddies imagination" but i stand by what i saw.  
someone contacted me through friends reunited where i posted about it to say they had seen a ufo near the school years ago too and my middle nephews dad saw two cigar shaped objects (one blue and one red) over the school as well.  he lived in a house that backed onto the school.  he took a photo but nothing came out when it was developed. 
ther have been other sightings reported in my local paper over the years of strange things in the skies around here.
 this is my third submission to this site.  i stand by what i saw and am a completely sane person who works in local government and am about to have my first child.
