As a kid, we, my younger brother and I, were playing in our pool. He asked me to help with an underwater handstand. I held his ankles, but he never did say when to let him up. He spent a week at the hospital in a coma, but did not survive. I got disowned.
Rising Action
So, of course, after 15 years, my dad and I had to meet at a gas station. He didn't recognize me, so I asked him to give me a ride to the new restaurant that opened in town. Being the nice person he is, he said yes. We had dinner at the restaurant, and he offered to pay, but didn't have enough money. I paid, and he offered to have me as a guest at his house. I agreed, but said I had to pick up some stuff from my own house. This was the perfect time to start my revenge plan.
Climax
At my house, he used the bathroom, which gave me the perfect opportunity to run up to my room and grab my backpack (which was filled with explosives). At his house, I would set the bombs. On the way to his house, his car broke down. While he was looking at his phone, I fixed his car and stuck an explosive in the engine, setting it for 2 o'clock am.
Falling Action/Resolution
That night, instead of sleeping, I planted bombs all over his house, and set them to explode at 2 am.
The next morning, I left the house at 1:45, to get as far away from the place as possible. The bombs went of at 2:00 sharp. Soon, the police arrived at the scene. There were no survivors.
Unfortunately, the police station wasn't too far away, and even though I pleaded innocent, eventually, they figured out that I was the culprit. I admitted everything, and was sent to an insane asylum.
