I ignited the sheets because they were a little dirty
Why would you try to deal with your sheets by burning them?
I thought about sending them to the laundry, but I figured I could clean them up myself.
Lighting your sheets on fire to clean them is extremely dangerous. If you need to clean your sheets you should simply put them in the washer. If you continue lighting things on fire the them you most likely end up burning your house down.
Just because it's dangerous, that doesn't mean I shouldn't do it. Fun is all that matters in life anyways.
Fire does not clean things; it only destroys things. Trying to clean your sheets by lighting them on fire was just destructive. Next time try the laundromat.
