Sometimes it's the International Space Station going overhead. There is supposed to be a great sighting opportunity tonight. Check your local info, but here in NY it will be about 8:53 pm, if I remember right. It will be nearly 80 degrees above the horizon at maximum elevation, so it's highly visible. You are looking for a really bright, relatively fast moving dot that does not bink. (Airplanes have blinking marker lights; the ISS glows steadily.)
Sometimes it's just the clouds. We like to look for shapes in them... I have never outgrown this, and I sincerely hope Mikro never does either.
And sometimes, it is an utterly breathtaking sunset. These are not in any way retouched. The sky really was this gorgeous! If you remember to look, you can see beauty even in a supermarket parking lot.
