Yeah, I see where you’re coming from. Although instead of laughing I’d probably reply with “sounds like it’s time for a story.” Because I think I would assume that something happened to them recently that highlighted the danger of fire lol

“Presenting something well-observed and well-documented as a novel thought is laughable.” I really like this sentence. It made me realize that I’d interpret “laughable” as either “humorous” or “ridiculous” depending on the context. Specifically regarding how genuine the person is being, which is impossible to be sure of. You can only make assumptions about whether a person is being genuine/honest, although you can get more comfortable with those assumptions as you get to know them better.

Those types of “hey did you know water is wet?” comments can also serve as a jumping off points for sarcastic remarks with friends.
