Friday's Forgotten Commandment

Thou shalt not partake of thy friend of thy friend's attempt at preparing 'international cuisine', then spit from thy mouth the bite of was-that-chicken-or-some-kind-of-asparagus? into thy napkin and leave the napkin stuffed with seriously-what-was-that? beside thy plate for the duration of thy meal, only to discard thy napkin into the rubbish bin when thou thinkest no one is watching thee, for it art one of thy friend of thy friend's favorite napkins that they inherited from their grandmother.
