It sounds like a Hardy-Boys Story. Here it is:
So I’m staying at my friend Alena’s, who is tomorrow leaving for a vacation with her Step-Mother, Barbara (they are good friends with each other, despite the age difference). Barbara is spending the night, and I headed out with friends to give them time together. They apparently had a lovely dinner of Spaghetti Bolognaise, cooked by Alena.
When I returned, and eventually headed into the bathroom, I saw telltale signs of tomato sauce and oil. It looked suspiciously like Barbara had found Alena’s Spaghetti Bolognaise so unpallatable she simply flushed it down the toilet.
Dare I bring this up to anyone? Decorum, the better part of Valor, suggests not.
