I have this extreme dislike for people using 'aku-kau/ko' when talking to me unless that person has use it since day one he/she talks to me.
It upsets me so much, especially if he/she uses it when he/she is mad or upset at me. To me, that is rude and I get extremely upset when someone being rude to me.
Yes, I've been rude to you once before…but what did I get? What did I do to make it up? Have I ever done it again?
Mind your language…
