Because a woman will always be a woman...
The Indians are quite not too adventurous. Especially in India as a matter of fact.
Having my (female) assistant to come to a meeting in the evening was really not easy, the whole office talked to the parents and her brother-in-law came along... What are the parents afraid of I don’t know, but they were damn scared. Obviously, given the act that I am a foreign girl, all alone in India for 6 years, it is difficult for me to fully understand. Though I respect it.
And this kind of attitude is not the exclusivity of the lower middle class people. For example my upper-upper-class girl friends have “crapped me a watermelon” – this is a French expression translated by Bing and I found it too funny so I left it!! It means they made a big fuss – the other day because I wanted to drive home at 2 AM. And according to them it is not safe (for the girl, not for the others, I see you coming! – though in my case I would think I am the danger...).
They have for example asked me to put on a sweater over my dress. And I drove home safely, and without my sweater.
When I told an Indian female friend, who is now roaming around Vietnam that I intended to do a road trip from Delhi to Mumbai, she told me without hesitation "no you can’t do that! I told her to stop being an Indian mum...” That said it's funny, a French girlfriend also told me I was reckless!
