Matt Roloff and Caryn Chandler to Zach and Tori: You Suck as Parents, Let's Make Up!

In my opinion, the final season finale of "Little People, Big World" did not confirm the end of the ongoing feud between Matt Roloff and his son Zack.

I loved the episode where Roloff's farm celebrated the busiest and most prosperous time of the year, pumpkin season.
However, Zach and his wife Tori chose not to attend or help.

The question I had was, what was the basis for this refusal?
First, Matt decided to put part of the lot up for sale...and then offered his children a deal to buy it.

Zach didn't just refute that statement.
