Approach a girl

I was approached by a guy on the street we were just passing by against each other. he noticed me and stopped me to give a compliment. I felt strange and wierd because it was all of sudden. I never saw that guy before.

It looks creepy actually in general.

Seems I was not a random person we live near to each other (saw him again after few weeks passing by at night without making any eye contact but I felt it was him) so he has seen me quite a few times.

For showing guts to approach and tried to initiate conversation, I will say 10/10 for making efforts.

But I will say should not do it.

If u made an eye contact and she also made it and u both smiled at each other u can say hi.
Take it slowly. Start with waving hi then gradually approach and talk to her.

God knows what "special skills" these fbois possess, just came back from friend's flat, there was a jobless, no hardskills, mba coaching goer flatmate, b*nging a girl he picked up from a shopping mall this evening.

mind you this in Ahmedabad, no clubs/bars/pubs.

Get off your phone, go outside and hope an extrovert adopts you, you’ll slowly get accepted back in social society and get the confidence to talk to a girl.

Or do what most people do, have a couple of drinks and say bye bye(temporarily) to your social anxiety

That sounds creepy

unless you are absolutely gorgeous or have a lot of money or something to show off for (it's reality, let's accept that) it won't work in India.
I believe girls in India look for safety hence they need to know something about you before you approach them, so in my opinion the best way is to meet via mutuals.
