Maybe I've been abducted a bunch of times. Who would know.
I've heard my partner to use that excuse to explain my actions...
On a serious note, we see quite a few UFOs here. The disappearing 'noiseless helicopter' was my personal favourite. On dusk, looking out over the deck. Appears in the distance, moves up and down a bit and then just vanishes.
About 20 years ago I was driving with a friend on a long trip. He was working as an air traffic controller. We see a light in the sky which follows us for about 20 km and then just vanishes. He says "<expletive>" and I agree with an expletive of my own. In his opinion it isn't a plane.
One more... My partner and I were heading to Queensland for a holiday one evening when we saw a light off to our right. There was a truck behind us. No side roads for about 40 km and the truck had its lights on. We keep watching this thing out the window and suddenly it's gone. And so is the truck.
