Maybe you see things differently, but perhaps there is something more interesting and constructive you could say than: “You both failed at life.”

I certainly see things differently. I see a person who wastes time in the Internet instead of trying to fix what absolutely should be fixed - it's not that we have all the time in the world to make things right. Look at the part you quoted - "before she passes". The guy realizes that the mother may die, but still, talking crap on the Internet seems to him like the better choice to spend the precious time left on.

For me, selecting Internet upvotes, virtual handshakes and high fives by random, anonymous nobodes, over family is certainly within the definition of "failed at life", and I'd sooner bite my own tongue off rather than approach such a person with "interesting and constructive" words.

Of course, arguing online is pretty fun…

Definitely! 🧐
