In Italy, heavily scented candles may have your guests wondering what kind of housekeeping you're trying to hide.
To put yourself above suspicion, burn "clean linen" scented candles for hours BEFORE they arrive and then hide them all (Italians have an inherited, genetic adoration of clean linen - you can sucker punch them in their great-grandmother's bloodline with a little help from Yankee Candle).
Host classy, people.
