My garage floor was really dusty so I cleaned it up with some gasoline and a mop.
Using gasoline instead of water is very unsafe. Why did you do that?
I was too lazy to fill up the bucket with water.
Gasoline is a dangerous and highly flammable liquid. Using it as mop water is grossly irresponsible. You will eventually set your entire garage ablaze if you continue doing this.
I'm okay with it.
Even if for some reason you are ok with your garage catching on fire, your actions could cause damage and injury to your neighbors. They didn't do anything to deserve to have a fire you started travel to their property. Gasoline is an extremely dangerous substance, and for the safety of those around you, you need to be careful with what you use it for.
