Obviously the first mistake is eating more chilli peppers than one can handle. Been there, done that and survived.
The second worst mistake is knocking the table’s container of fish sauce onto your shoe. Good shoes are hard to find here, so I was relieved that enough detergent, soaking and sunlight eliminated the fermented fish smell.
Yes, I do season some foods with fish sauce. Didn’t at first but have acquired a taste for it.
