saw very large saucer shape low 300ft. hovering ufo craft

round dim white or gray disk shape one-hundred yards across blue dim lights on bottom of craft about 500 feet high in sky  it was just hovering above absolutely no sound i just looked while driving and there it was hovering above the street we looked by stoping about one minute became afraid and drove away it did nothing i had just pulled out on park road out of a apartment building we disgusted the craft while going to a movie that nite my friend and i did not know what we had just wittnessed my girl friend was without words as to what to say i suppose leaving was the smart thing to do we were not talking about ufo's that nite but we saw one we both knew  strange afterwords days later we just shut up and never talked about it anymore but it seemed as if 5 minutes had passed getting to the movie but actually about 25 minutes had passed i pondered the time of this incident and it has always puzzeled me but i know we weren't taking up or anything like that we just observed the sighting of the extra large silent saucer craft
