CONFESSION: I totally bought a "diamond candle" (not MLM, off a website) as a joke Christmas gift/ stocking stuffer for 10 bucks last Christmas for MIL. She told me a couple months ago it was her favorite gift. Erm... I don't think she got the "joke"
because if everyone buys this stuff to help someone else earn money on the side then that purchaser will also have to have a job on the side to be able to afford that and earn some extra money for their families.
