I used to have a friend who lived 2 doors down from me, when I was around the age of 10. I once was walking from my house out to theirs, and a mockingbird, widely regarded as one of the meanest birds, came down on me as I passed underneath at tree. It pecked me in the head, and I started to yell and run to my friend's house, while the bird pecked at me and repeatedly attacked me until I was within the protection of their home.
A few hours later, when I had to LEAVE my friend's house, I was not expecting the bird to still be there. However, within 5 seconds of me walking outside, I was once again being pecked in the back of the head, all the way until I got back inside my house.
It was pretty funny.
