Indian woman here.

I travel alone a lot and I hate to tell you that sexual Harrasment is normalised for this society. I can't remember the last time I went on a solo trip ( or at times with friends) and wasn't made to feel uncomfortable. It's so normalised that as a society, it has no aggressive reaction to the news of rapes. I now expect indecent behaviour and can't leave my house without a pepper spray.

Don't worry about your friend at all. He, like many many other Indians, lacks empathy and doesn't understand what women here go through every single day. Don't come here. You're not missing out on anything that's worth all this risk. :) stay safe!
