The "I know, crazy idea." from the parent comment is even more abrasive.

Calling out every abrasive comment would take more effort than I'm willing to expend, and would itself be pretty abrasive. So I picked the comment where they called Covid (the event where many people died, had their businesses ruined, etc.) "fun" over the one that mentioned work-life balance.

The person you're replying to asked if it was fun. Consider that my sarcasm was meant to be sort of tongue in cheek and not incredibly serious, which is a very different kind of tone from other comments in this chain.
