Lloyd in Space

It's Bolts birthday party and Lloyd is the only one who turns up. While poking around, he finds a video of what Bolt used to be like. She was really nice and had a soft voice, but new models came out and she grew old. Her husband and her are fighting when they come in from the kitchen and Mrs Bolt decides she's never going to teach again. Lloyd shows the video to everyone and they show up, hoping she'll come back and be nice. She does come back. But she's not nice.
