お〜する to refer to others?


Common wisdom holds that verbs such as “お話しする” are humble and are generally
only used with the speaker as subject and certainly not used with a superior
as subject, but I encounter this all the time, for instance:

The context being that this is the parent of a teacher, who is also the owner
of a big company who is estranged with said teacher and the character in the
picture works to remedy their relationship yet uses “お話しできます” with this
character far higher in status as the subject. Indeed, when I went to look up
after encountering it whether I missed something I came across [this
source](https://bunpro.jp/ja/grammar_points/%E3%81%8A-%E3%81%99%E3%82%8B)
which states:

> This type of speech is used to refer to the speaker and their actions. This
> is opposed to honorific language, which refers exclusively to the listener
> and their actions.

But then comes with this example sentence

> ご登録する方はこちらをクリックしてください。

This example, clearly using “ご登録する”, together with 方 even for others.

What's going on here? Because I see it all the time that verbs such as
“ご到着します” are used to refer to the actions of others, often those above the
speaker in status. The reverse is not true. I've never seen anyone refer to
himself with “ご到着になる” nor have I seen “ご到着いたします” for someone except of course
for trains which are part of the in-group of the announcer.




[謙譲語]{けん・じょう・ご} (humble language) is not only used to humbly refer to one's
own actions, but also those of other members of your "group"/"side". So in
this case, the 先生 is the object of respect/honour, and even though the girl is
speaking of her father's actions, the dynamic is such that the her group (in
this case, she and her family members) behaves humbly with respect to the
relationship with the 先生.
