Kos writes about whining. I think it’s important to remember, and it’s applicable beyond the political realm, too. And it reminds me of thoughts I would have whenever classmates would complain to the teacher (or professor; this happened in college, too!): “I meant to do the homework, but…” or “I wanted to finish the paper today but…”
Actions don’t just speak louder than words, they’re more important. In many cases they’re all that matter. I still need to be reminded of it from time to time.
It’s also worth noting that, in many cases, we are incapable of action, or too busy with other action to handle more. I’ll leave it to the reader to decide whether whining or complaining is worth the bother in those cases. (Sure it’s more complex than this; sometimes words are a form of action, but that’s not whining, that’s acting.)
