Is it rude to greet our elders in english, instead of our native tongue?
Should we establish a standard for greeting elders, instead of saying "Good morning sir/ma" should we greet them in our native tongue like;
" E kaaro o"
" Ụtụtụ ọma"
" Barka da safe"
" Aje & Otofe"
" mingwo" etc
I've observed that even when we greet in our native tongue, we do tend to add the english word sir/ma to it. Is it still rude to greet them without adding the english word sir or ma? I've been wondering if it is proper and polite to greet our elders in english or native tongue. From my observation so far, If an elder knows you are of the same native and you greeted him/her in english. I think they find it rude and disrespectful of you.
I need your views on this issue my fellow country men and women. Thanks!
