I don’t think your cousin’s wife is ‘brave.’ (I’ll leave it at that).
Well bravery is all relative. I am not brave enough to go anywhere near a unrestrained lion/tiger, alligators in the pond in my condo complex in Florida, or the frequent snake visiting my parent’s house house in India, or try to kill a live scorpion. I have a real story of run-in with a huge black scorpion which still gives me nightmares after half a century.
