Detailed description: It was summer, and my dad was mowing the lawn (push mower). I was out in the sun. I had just washed my hair, and was "sun-drying" it outside for some natural highlights. I was a teenager, about 16. I was looking up at the sky, and noticed a white-silvery disk-shaped object fly into some clouds. At this point, I thought it was the Moon, and that the clouds had moved "over" it. A few seconds later, the object came back out in the opposite direction, along the same path ... there was no way that the clouds shifted position like that. I tried to get my dad's attention for him to look at it, but it was gone. It was pretty high up, as these clouds were not low-lying, as I recall.
