Laura Ingalls Wilder (1) - S7-E1
Stupidity: Charles and Caroline are dancing at the church social. Charles makes a comment about Laura getting married. Caroline responds with "I'm just dying to call you Grandpa." Mary's son just died. Charles has already been a grandfather. That comment was beyond insensitive, and just plain stupid as written. She should've said, I can't wait to call you Grandpa again.
Stupidity: When Adam recovers from the accident that restored his sight, one of the first things that he wants to do is take a drive with his wife. He lost his sight as a young boy. I doubt that he could handle a rig without being shown how. Would you trust him?
