ok here my thing. I love, respect, honor and cherish my husband. Yet, to call him by Aap or the english equivalent being "sir" or something similar, just will not do at all. He is my best friend, my life partner, the father of my children. We MADE CHILDREN together. Call him "sir"???? I giggle at the thought!!
How can one call "sir" to one you get jiggy with?
Sorry...no disrespect intended here to those who do this.
The word Aap does not equal to 'sir'....sir is just sir in Urdu as some English words can't be translated. Maybe 'janab e aali' but that also doesn't really define 'sir'.
