Night had never really considered this aspect of things, coming from a Muggle family herself. However, she knew a lot about do's and don'ts in the Muggle world. Would voicing those make any difference?
"
Well, I'm kind of new at this wizard stuff, but I think there are a lot of do's and don'ts in the Muggle world, too. Like, for instance, you don't wear socks with sandals generally, or more than one pattern in an outfit, because that hurts people's eyes." A lot of that was probably pretty universal, wizard or Muggle. "
Also, you don't wear shorts in the winter. I imagine that could be a specific thing not to do as a wizard around Muggles, as well, because there's probably some charm you could do to make your body not get cold,
and then Muggles would think there's something weird going on."
