Cell phone nudism. Nothing wrong with having a quick convo while nude at the beach!
Anecdote:
I was at a nudist resort once; one woman was pacing naked up and down the pool area while engaged in a very active conversation on her cell phone.
I overheard bits of her conversation. Obviously she a business owner or manager, conducting business while enjoying some time nude at the resort. I smiled to myself, wondering if her client/customer knew that they were actually having a business chat with a completely naked woman!!
I love the world of nudism!
