the mysterious black gunk

My mom was sitting in bed and noticed some black gunk on the sheets. She thought it might be a Reese's Pieces Bite that she had been eating earlier. So she took the sheets off the bed and washed them. The black stuff was still there after being washed. It didn't smell like chocolate and it was like an adhesive.

Mom noticed a spot on her leg that looked like a mole. It was new and it didn't have good borders or coloring. She tried to be observant about that sort of thing because I have had moles removed that may have turned into cancer. She made an appointment at the dermatologist.

After sitting down at the recliner, my mom noticed the black gunk all over the foot rest. She yelled for Dad to come in there and look at it. She asked him if he had seen anything like that before. He said that it looks like the stuff that is all over his boots. Mom went and looked at his boots. Sure enough it was the same thing. My dad had cracks in his boots and instead of going out and buying a new pair, he put some industrial type adhesive on it that he had found at work.
Needless to say, he is in the doghouse now.

After examining her new mole again, Mom tried to pick at it and noticed it could come off. It was the black stuff from Dad's boots! She thought of the embarrassment she would have gone through if the dermatologist had picked it off. She cancelled her appointment.
