Ordinary Banana

This happens once a week: me: <learns a thing by doing it> me, on twitter: "I'm doing XYZ" rando: words that boil down to "oh, you just wasted $200 and are going to have to deal with a mess because you're dumb and did the wrong thing" why do people do this?

2/ examples include: the brand of chainsaw I buy, the manner in which I stack my firewood, the kinds of plants I grow, the details of my off-grid energy system, the way I store feed for animals, etc.

3/ This annoys me for two reasons: (a) the absolute voice of authority: "you obviously don't know X but I absolutely do, so let me tell you how you're wrong" (b) the timing. You might warn a friend away from marrying someone BEFORE hand, but afterwards? "ha ha, dumb move!"

4/ What sort of response do people expect? "Oh, thanks, that's a good point. I guess I'll just throw away my new barrels and chainsaw, and plow under my pumpking patch, and tear down the new fencing I put up" ?
