ok, been considering something this morning that threatens to become one of those 'Things That Keep Me Up At Night.' if Vulcans mate only every seventh year, how is it that a Vulcan couple gets their mating cycle synchronized? do young Vulcans put ads in the the Pon Farr Times: "SVM seeking logical, detached and efficient female who mates during late August/early September of 2006, 2013, etc. I am a logical, detached and efficient male who enjoys lifting my eyebrow, saying 'fascinating' and being condescending to humans. ISO same. include photo with reply."
