A decent starting point is to assume that unquoted punctuation is
special until you verify otherwise (assuming you don't actually
want the special behavior). Even then you might as well quote it
to avoid confusing your future self.

Presumably you've internalized that "*" is a globbing character,
so you wouldn't be confused if this printed a bunch of filenames:
echo *.txt
Once you know that "[" is also a globbing character, it should cease
to be confusing. That said, remembering all the globbing characters
can be a challenge, especially the ones you don't use regularly.
