I learned this the hard way. Socks are religious pilgrims waiting to happen, and whether pillowcases, non-fitted bedsheets or even tees, they’ll journey within anything to escape dryness. Underpants only slightly less so.
Despite it being contrary to green / energy-efficient recommendations, I wash and dry my bedsheets separately from smaller articles now.
Why are you washing a duvet cover with the rest of your clothes? Shouldn’t it get its own cycle?
Commas are important.
“climb in my brothers”
Means something different than
“climb in, my brothers”
Unless you button/zip it before washing. Then it’s just the fitted sheet scooping up my underwear shouting, “Band together comrades we are stronger together!”
