Have any of u seen a UFO?

When I was a little girl I rememer seeing three big pulsing green lights in the sky hovering and then they just zoomed away. They were in a triangle. It could have been three UFOs or one big UFO with three green lights. By UFO I mean unidentified flying object - wether it was an alien ship or just some sort of plane or aircraft from Earth, I don't know. But I never saw anything like it again, and I remember feeling very scared.
