I couldn't agree with you more...!
Not me, but my daughter....she went on holiday to Thailand about 10 years ago. She too fell asleep in the sun (why did no-one wake her?
) with her arms folded up behind her head.
She had sunscreen on (almost!) every part of her body....except that soft, pale, vulnerable bit on the inside of her underarm, just underneath the armpit.
She ended up in a Thai hospital with severe burns - completely out of it and vomiting. She was in there for days.
To this day, there are white triangle shaped marks on her perfect body. Please beware....
