Blowing up the air conditioner

My dad did his very best to take care of me when I was a kid. The thing was, he was a very young man when he had me, so growing up it felt more like he was a fun big brother than an actual father. This lead to us getting into trouble more than once, but his heart was always in the right place. One summer, when I was 9, he took me with him to a job site, where he had been working construction. Since I was there I wanted to help and I tried to assist him in setting up a window mounted air conditioner. I slipped, then the AC unit slipped, fell, and landed right on my ankle. That heavy air conditioner shattered the bones in my foot and lower leg, and left me in a cast for the rest of the summer. My dad felt terrible about it, and did his best to cheer me up. When nothing else worked, he actually brought home that very same AC unit that had injured me so badly. I was confused at first, until he also showed me a bag of fireworks and huge firecrackers that he started stuffing into the air vents of the machine. He said that since the air conditioner had hurt me, we were going to hurt it back ten times as much. I know that it is quite impossible to “get revenge” on an inanimate object like an air conditioner, but I have to admit that it felt great to blow it up!
