The thing which most annoys me in the world are people who pester you or hurt your pride. Why can't they just lead their own sweet lifes and let other people be. I really hate people who mess with other people's lifes. Everyone should be free to walk the streets alone at which hour they like without having to worry about that kind of people.
I really hate it when they insult you or through something at you. Especially teenagers.
When I was in school I had been bullied quite a lot and once an unknown teenager caught me in a bad mood. Theys were like 4 teenagers on bicycles riding in front of me and I was behind, just riding my own way. Then one of them started saying to his friends: "Look at that dickhead" and then something made 'click' in my had and I rode at full speed into them. We fell and he stood up, obviously surprised and said to me: "as*hole!" Then I punched the guy on the nose till it bleeded and I took his head in an arm grip and lowered my mouth to his ear and made a growling noise.
Afterwards, my parents and the teachers forced me to apologize to him and they were all shocked, saying: "Oh, I am so disappointed of him, I never thought he [i.e. me] would do such thing!"
I apologized and afterwards the guy bullied me and I had to alter my way to school, in order not to meet him.
