I admit I had not heard that about river goddesses. You learn something new everyday, huh? :D
I definitely relate to outside being expensive, though not sure if we have such a saying in my country. Especially now, everything seems to cost twice more than it did when I was small and just getting used to "the cost of living". I thought it was expensive then, let alone now! xD
Your beach looks lovely, and the water looks delightful to swim in. I totally get you on liking to swim naked, though! Maybe you could go on your own sometimes, if you feel uncomfortable with your family seeing you swim naked? Or is that not allowed at this place, at all ?
Anyway, thank you for your participation to the #KISS prompt. It sounds like a great (and low-key) way to recharge. Love it.
