How do I talk to someone explicitly?


明日の朝おそいおきたら、にどねないよ！ Given this phrase in this Context I’m not sure if I talk
about myself or if I talk to someone else like I intend to do.

I could add あなたは at the beginning but I know this is impolite unless I use the
person’s name to be more accurate.

So without knowing the name of the interlocutor, how people usually deal with
it?




So did you actually want to say 二度寝するな ("Don't sleep again")? Then an
imperative like this is naturally addressed to someone other than the speaker,
so you don't need (or can't add) a subject. You don't need a subject even in
English.

If you need to explicitly specify the subject, you can use the ～してはいけない ("must
not") construction and say something like アリスは二度寝してはいけない ("Alice must not
sleep again"). Saying this to someone in front of you can sound like a preach,
though.
