New Life Rule
(slrpnk.net)
Be sure to follow the rule before you head out.
Rule: You must post before you leave.
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.
