On a long, long flight from Amsterdam to Singapore about 10 years ago, I was seated next to a very pleasant Vietnamese woman who was going back to her native homeland for the first time in decades. With her was her 2 year old granddaughter. After about 45 minutes into the flight I noticed that the girl had soiled her diaper. Not a problem I thought… I have kids and she just needs to be changed. No, no, no… For the next 10+ hours she did not in fact change the diaper, but simply from time to time poured some really bad perfume down the child’s rear end, immensely compounding the problem. It was everything I could do to keep it together having to endure this awful bouquet that was now overly pungent.
