Dear egocentric loonies around the world,
If you don't—or refuse to—do something, say “I don't do that,” not “Nobody does that.” Because, as I observe, that's most likely a lie.
Specifically, if you like A over B, you don't say “Nobody does B anymore,” because, chances are, you aren't paying attention to B enough even to notice there are a lot of people who do B.
Much love,
Eugene
