The boomer was given a designer shirt when they graduated high school. At the time, the shirt cost roughly half an hour's wage and will last a lifetime.

The other person's shirt isn't actually a shirt, but a series of rags tied together and is shared between 3 other people. Those rags cost roughly 6 hours wage per person and constantly rips. A comparable shirt to the boomer would cost 40 hours wage. The other person also received no help with buying their shirt.

The boomer doesn't apologize, but instead blames the other person for spilling the drink. The boomer doesn't provide a remedy for the problem, but suggests that the other person should just not have a stain on their shirt in the first place. They then purposefully make the stain worse, because they earned it.

They then tell the other person about how when they were their age, they bought a worse shirt with a bigger stain on it while making less money, and turned it into a clean designer shirt. They call the other person lazy, and tell them they need to work harder to get a better shirt.
