haha nice topic dushwari,
my husband grew up his whole life in europe, so i wasn't expecting him (because of his upbringing and age) to call me begum but as a newly wed, when i heard him call me 'begum' while referring to me infront of my parents it was kinda funny and cute..
my dad used to call my mom begum in a distinct way... and when my mom heard my hubby call me begum in pretty much the same way, she found it really funny too.
normally we call each other by first name, but he throws in begum once in a while and its just kinda funny i dont know why.
