As you probably know, interactions with women don't work here quite the same way as in Finland. Things seem to be a bit more complicated. And for European women in here that's not a good thing - it's quite usual for Western women to get grabbed here by their asses or so. Locals seem to think that because the interactions between men and women are 'less complicated' in Western countries it means that they are easy prey and they give anything to anyone who wants. I have heard quite some complaints about these things from female friends.
Today I asked my colleague Gaurav at the office about dating. My plan is to bombard him and Amit with questions about the Indian culture and let you know what I have discovered. So I started this today.
Basically, there are two approaches. Either fixed marriages (which are the most common types of marriages here, still) or the more 'liberal' approach which sounds more normal compared to our ways. Marriages in general are here not about marrying two persons; they are about marrying two families.
In fixed marriages, typically the family of the boy thinks that one girl might be suitable for their boy. (Or, rather, that the girl's family might be suitable for their family.) So they go meet the family. Slowly they decide that their families should get married and the marriage is arranged. I doubt the kids' opinion is asked much.

If you are a renegade, you may try to get acquainted with a girl yourself. You take the girl out a few times and see what happens. It is a tradition that the boy pays for everything when they are going out. Basically, this can go as far as kissing and maybe touching the other, but surely not in any sensual places. And if you wish to go further, you need to marry the girl. Most guide books about India mention that girls are quite well protected before marriage - if they do anything scandalous with a boy before marriage they pretty much lose their face. And this is why their families protect their innocence furiously.
Indian weddings are something interesting also. As an event. Basically both sides have to invite their whole family to the wedding plus a lot of semi-random friends. For example if someone at the office had someone in his/her family who is going to get married, I would probably get an invitation. So, a wedding with 1000 guests is nothing unusual. It's rather small, actually.
So where and how do they have these weddings? If you are poor, you either pick a small street, block both of its exits, put the street full of tables and arrange it there. Or then you go to a public park and arrange it there. If you have money, you arrange it in a special place somewhere around the city.
And the costs? Well, if you organize a wedding somewhere near the city center, the rent for the place can be 25 lakhs. A lakh is 100 000 rupees. If you organize it somewhere not-in-so-center-place, the rent might be around 1 lakh. But that's only for the rent. People also need to eat and drink. Plus other stuff. If you have ever organized a dinner outside, you know how much food and drinks cost per person. Multiply that by over a thousand. Ok, this is India, things are cheaper. But still. It's.. a looooooooot of money. I tried asking how they get this sort of money but I didn't get any proper answers. Or maybe I just forgot.
Considering all of these facts (and Kristīne), I think I will not get a girl from India. Sorry.
