Shirt Is Used As A Shoe Cleaning Rug

I just come out of the woods and my boots are really dirty and muddy - good that Ive my slaves fresh washed white shirt hanging in the car ;- I throw it in the dirt so I can stomp and rub my boots clean on it. Some of the dirt is really sticky so I grab the shirt and use it as a cleaning rug before I throw it back on the ground. When my shoes are somewhat clean I get into the car and accidentally drive over the shirt a few times ;-.
