This is probably true. ... It doesn't say much about us, as a subset of humanity, does it?
The long-time summer athletic coordinator in our summer home community had a firm, often-reiterated "no whining" policy for the kids. No complaining about other kids' performance, no complaining about officiating - you're blessed to be here, to be healthy, to be alive. No whining.
I don't always live up to that... but it would be nice to think I try!
