Long term sightings of UFOs.

I have lived at my home for 15 years, and in that time I have seen around ten UFDs. Always in the same direction over my back garden. I just saw one tonight whilst I was washing up. when I looked up and noticed it I went for my binoculars and then it stated to move away when I started to look at it.

It was if it was watching me, I got to thinking does this mean that I have probably been abducted? or why do they hang around the same area over the years
