I think apsurd interpreted Lammy’s post as a complaint, like the firefighters are too gleeful.
Then apsurd is pointing out that there’s no reason to complain, and they shouldn’t waste time with remorse.
I don’t think Lammy actually meant it as a complaint, though, which ended up making apsurd’s correction confusing.
Anyway, I think everyone in the thread agreed: park in front of the fire hydrant and nobody feels bad but you as you get your window smashed. Broad anti-fire consensus.
