A wasted slice of pizza.
A plate of food. Yes, I did find one once. Couldn't figure it out, had to wash the cushion too.
I was visiting a friends home located out West. He and his wife have 8 adult children and a slew of grandchildren always visiting. Once a week she pulls all the cushions. Usually she finds loose. The day I was there she found a very dirty diaper that was rolled up under the cushion. After someone sat on it the contens squished out all over the little sofa. We had the drag it outside to be cleaned.
We found a smashed mouse long long time ago.... 😣😫😝😲😨
An unidentified stranger's clothing.
