I was outside on the basketball court, talking with my teacher. My friend saw it first and told me to look. I saw about 18 tear-shaped objects in a bunch with space in between. They were shiny and silvery. The skinny point was forward. They moved from North to South over the school. Then they turned East, formed a spiral, then a line where they all pointed East. Then they went over the school and I couldn't see them. When I walked North to get another look at them, they were gone. The whole sighting lasted about a minute and thirty seconds.At first I thought they were birds, but then I saw the tear shape. I felt confused at first and wondered what they were. Then I talked to my teacher and he said that I was right about how they couldn't be birds. Then I said they couldn't be planes either because they were too small. At school we didn't talk about it more, but I kept remembering what I saw.Now I feel normal about it.
