I dated a girl, and every time she came over, I noticed little, oily smudges on the armrests of my couch. At first, I assumed it was just an accident, possibly from lotion or something spilled. However, even after properly washing the couch, the smudges resurfaced.

Curious, I observed her intently one day and eventually caught her in the act. She was absentmindedly plucking at her head, collecting dandruff and oil on her fingers and wiping them on the couch.

Here’s another story. When I was 17, I went to spend the weekend with my ex-boyfriend. This was my first weekend at his residence. He always looked and smelled good. In the evening, he escorted me to his bedroom, where I could sleep in his bed.

The sheets were brown. They had not been changed or washed in at least ten years. I had nowhere to go, so I entered. The odor was terrible. He lived with his mother and father. Following that, I left him. I sent him a message requesting that he wash his bed coverings.
