Pasta sauce spill becomes neighborly dispute when pugnacious neighbor piles on top of an already bad day: 'He started lecturing me loudly about being irresponsible and how people like me don’t belong in shared spaces'

There's no use crying over spilt milk…or pasta sauce… or any other foods ranging from liquid to semi-solid. 

There's nothing worse when you've already made a mistake than having people piling on. And it didn't take much for this neighbor to launch into berating them, lecturing them for their mistake as they scrambled to clean up the mess.

This apartment dweller might have dropped his groceries, but that didn't mean that the neighbor was willing to drop the subject.

Undoubtedly, this neighbor has other issues going on in their life and is already walking a razor-thin edge of mental equilibrium. Still, it's difficult living with or near anyone who seems to be looking for any slightest excuse to react. And, when you live in such close quarters with strangers, with only a paper-thin wall separating your existence from theirs, you're going to run into issues, since any unnecessary noise draws immediate attention.

The neighbor could have stopped to help out, which would be the neighborly thing to do regardless of their other feelings toward their neighbor, but instead they chose to kick them while they were quite literally down. After some hand-waving and attempts to de-escalate the issue, the apartment dweller finally had enough and snapped, putting their neighbor in his place.
