Re: Parents make life so confusing at times :s
If you are a working woman then I am taking the liberty to say that you are fairly independent as well. Plus you are going on a business related trip there is no question about "dekh lo soch lo" crap - it is part of your work that you have to travel and your parents need to accep that and get out of their desi mentality of keeping the girl at home so she stays sheltered and doesn't get hurt.
I say you tell them I have to go on a business trip to Egypt here is itinerary mama and I'll call you when I get there.
