There is nothing worse than to remain sober around those who are drinking.
Their euphoria intensifies, while you only grow quietly embarrassed for them.
At some point during the evening they will intuit you are judging their follies and become self-conscious. They will despise you for depriving them of the bliss of drunken excess by virtue of your watching.
The reaction is much the same from the gluttonous, rich, and powerful when one reminds them that the resources of the environment are not infinite.
They might continue to plunder, but they will hate you for bringing conscience into their debauchery, for turning the light on during the orgy.
'Why, the house was burning down, but we were so enjoying the glow…'
