what is the most annoying thing a visitor has ever done in your house?

I don't listen to music and am not interested in hearing music, ever... Once, a friend brought some guy over when my friend and I wanted to talk. The stranger (to me) had a guitar with him and kept playing it and asking me if I liked the music... That was definitely the wrong thing for him to ask... I asked if he heard any music playing in my house and, when he said no, I explained that was because I didn't like music and I wished he'd stop playing his guitar while my friend and I were trying to talk. He didn't take that very well and stormed out of my house... I closed and locked the door. My friend and I sat and talked. When my friend was ready to leave, we found the other guy sitting on my front porch playing his guitar to himself. Needless to say, I haven't seen that guy again. *shrug* We kept trying to talk but he kept playing stupid songs... He should have read the room better.

I remember years ago l bought myself a fluffy very white living room rug. A visitor to my house walked in and sat on the sofa nearest to the rug , then placed his feet -- with shoes on snugly in my white fluffy rug.

I honestly can’t think of anything anyone has done that was annoying . These things would annoy me though …… Not flushing the toilet Walking in mud on to the carpet Coughing and spluttering all over the food.
