This was spotted at Target, in their "Home Accents For The Genetically Risky Household" aisle we assume. Target understands that it's hard to find that special someone. At least with cousins you know you're starting your relationship with something in common (DNA). Where love chooses to bloom is not for Target to judge. Blood relatives can have at each other with wild abandon, unless they're same-sex blood relatives in which case the store will increase their already hefty donations to anti-gay political candidates.
