When I used to walk down the street every day to my school, I was always struck by the number of pigeons on the streets. Maybe is because I'm afraid of them, that I always pay attention to them when I walk. I remember when I was little that pigeons knew how to fly and when someone was near them, they flew very fast. Now they don’t even move. Another thing I have noticed is that sometimes they stay in groups on the roof of buildings and watch all the people go by. With my friends I always joke that they plan to dominate us. Which is very scary. Who knows, maybe they are taking the first steps to invade us. Sometimes I imagine that if this happens in the future, what would I do? This is one of my worst nightmares.
