The Betazed sensibilities on nudity are so different though that I think you can excuse the casual forms like that. We don’t really get a sense of Klingon nudity sensibilities though, so it’s hard to really put together the full picture.

He didn’t seem uncomfortable or harmed by it at least

Plus, we (humans) have changerooms with nudity and it’s relatively normal. I find it not very common now (in Canada), but it was when I was a kid. A month ago I was in Europe and had to use a communal shower, and there was a dad and a kid, which was weird but also totally normal.

So I dunno, yes, weird to do that without consent from mr woof, but I don’t think it was inherently wrong.

Taking me to a spa is 100% something my weird grandma would have done (she took me some weird places back in the '80s). There wouldn't have been any nudity, but she was a Republican, not a Betazoid.
