When I came home from school, I gave Mom a better explanation about what happened on Monday. She decided to make up her mind, and I knew what was happening.
So today we had a family meeting, and Mom told us we needed to sell the pig. She said the pig had a very "unusual" personality rather than a average one, and that Manny shouldn't treat him like a regular toddler. Besides, Manny has pretend friends and dislikes the entire "making REAL friends" concept, so he didn't like the fact that Mom was selling him.
So in the next few days, we're gonna secretly hide him until it's time for us to sell it to a pet shop.
