Knowledge: Golf got popular in 2000 after Tiger Woods won every weekend. On the other hand, houseboats became trendy in 2010 when the price dropped a lot.

Conversation:
I love being on the water and especially on a houseboat! There is nothing like falling asleep on the water!
That must be really nice. It is important to not mistake a houseboat for a boathouse, which is actually a shet used to store boats. Have you ever seen a boathouse?
I have not. Can you tell me more about houseboats?
Sure. Did you know that there are some houseboats that are not motorized? Those are actually moored and kept at a stationary point.
I didn't know that. Do you know when it got popular?

Response: Oh yeah. In 2010, houseboats got trendy because the price went down a lot.
