My mother taught me how to wash (in the machine), dry (hanging or the clothes dryer) and iron (dry or steam-cotton, synthetics, silk, etc). And I do a good job as any of my ex-wives will telll you. So I thought "how quaint, she is hanging my clothes out to dry, I haven´t seen that since the 50´s." So I butted in (as in what I was about to become). "There is no need to turn my socks and shirts inside-out. They will dry just as well without that effort," I condesented. I was politely told that that was true. However, the intense central American sun would bleach-out the color and in two months my white shirt would be "a sad white." So much for North American scientific arrogance.
