I recently went to Louisville for a couple of months to enjoy my vacation. I also wanted to get to know some laboratories of the chemical engineering department at the University of Louisville where I am planning to study for a PhD.
I rented a room close to the campus, and the first week I went to a nearby Kroger to buy some food. When I was there, I decided to buy a frozen pizza because I remembered I had been provided with an oven to cook. I chose one that came with an ovenproof pan as I didn´t have any kitchen utensils.
I preheated the oven at 400oF as directed in the cooking instructions and I was watching the oven frequently for the first 10 minutes. I also started the timer on my watch to take control of the time. After that, I went to the living room and started doing something on the computer that took my mind off the pizza. Later, I suddenly remembered that I was cooking something in the oven and looked at my watch and thanked God I still had one minute for the pizza to be ready. I stood up and headed for the kitchen to see how it was going. As I opened the oven´s door there was a huge cloud of smoke coming out of it.
I immediately tried to take out the pepperoni pizza, all of the topping slid to the floor, some of which fell on my hand, and I was burnt.
The fire alarm detected the smoke and went off. I was very scared and freaked out by this, since I did not know how to proceed in that circumstance and never thought it was such a big deal to burn food.
Finally, a man came over to see what had happened and realized that it was just a pizza. He told me to open the windows and the door to help the smoke go out and then the fire alarm stopped.

Any corrections will be appreciated. In addition, if you find the way I write weird or that a native speaker of English would never say that, let me know too.

Thanks!
