An observation

I had a long time friend come for a few days. When we got to the pool I told him my wife and I never wear suits but we would if he was uncomfortable. He said not a problem and I think he had his suit off before I even got to the pool area.
Turns out he's a nudist, but rarely gets to be nude outside due to where he lives so being outdoors nude for a few days meant a lot to him.

My older neighbor lady came by one evening for dinner at the pool so we all had our suits on when she showed up, after dinner we decided to get in the pool. She said she'd change into her suit. As she come out of the bathhouse I tell her to look at the new sign (clothing optional) over the door. She laughed and said she wished she'd known, she swims nude all the time at her sisters pool and uses our pool a lot while we're at work but wears her suit.
So maybe next time she'll come joins us sans suit.

Observation is; most people like to be swim nude, they either don't want to be the first to admit it, or be the first to drop the swim suit.
Other observation is the older we get the less we care about what we look like nude. It's more; I is what I is.
