A couple of days ago, I casually asked my Mom (without expecting any positive outcome) if she would grant me a supplementary card, and she merely smiled (which I could positively tell that she was considering).

Today, she asked under which bank would I prefer. I told her I was fine with any, so she suggested Citibank. =) Hopefully my Mom would get the forms soon, so I'd be able to be a Citibank Platinum sup card holder in no time. Woot!
