Help!
This is a bad idea from every perspective. We’ve all heard of people burying themselves at the beach because it’s cool and enjoyable. This is most likely her first time because we’d expect her to know better if she’d been doing it for a while.
She’s done everything wrong, from burying her head in a hole below sea level to doing it too close to the waterline. Worst still, it appears like catastrophe is on the way as water flows into her area. Hopefully, someone will be able to assist her in getting out of her situation.
