Nude around non nude friends

I see a lot of people here mention being nude around non-nudists friends or acquaintances. But it really isn't discussed too much.

For instance at a rented cabin for a ski outing or a mountain retreat sort of thing. I'd like to read some stories about this. So lets get started.
