This rule was forever burned into our impressionable teenage brains, and upon becoming roommates we (Dr Subtle and Monseigneur Rorschach) immediately agreed upon it. Having had previous roommates our definitions had both loosened- the "blue scrunchie" had been generalized to "handy cloth thing"- socks, belts, ties, pants, tshirts. This gesture was not a new one- it was a lazy copy of a stolen one. Until Monseigneur Rorschach innovated not a week back.
