on the street and one in the metro
1. I said how are you to one girl and she lifted her finger up and said NO!!!!!
2. I said hello, you look fine today to a girl in the mall - she looked at me like I was a sexual predator about to rape her and even turned a second time to see me again looking in disbelief
I approached from the face when they pass by me.
You can't approach women on the street. It never works.
First things first. You need a reason to approach. And first of all you must get a signal. A signal typically means a smile. I still get these smiles. But the smile doesn't mean much. It just means you are not a hideous autistic creepozoid fucktard. It means you are normal and maybe you have decent looks. But if you get the smile, you can say something. Usually you can approach say if she is next to you in line, next to you getting the stuff for your coffee, a helper in a store, etc. But you can only say anything if you get the smile. No smile, no words. The smile is an opening that can mean, "It's ok to approach me."
At this point in my life, a smile often means, "Well you are normal and goodlooking, so ok." Then if I talk to them, I get 'Why the fuck are you talking to me!?...I can't believe you are talking to me!...How dare you talk to me!" This is because I am in late middle age. At this age, I am not allowed to talk to any young women and I am also not even allowed to look at them. So in my case, the smile doesn't even mean ok to approach.
"How are you?" Not a good approach. What's the point of saying something like that. Say something related to the situation. If she is holding books, ask her if she is a student. Remark on her clothing or jewelry. Talk about the weather. Anything.
"Hello you look fine today." Catastrophically bad. Sounds creepy. You are opening with an openly sexual remark. Very bad. You can only say this after you know her a while.
Can't talk to women passing by in the street, especially going on the opposite direction. See other situations when it's ok to talk.
Approaching from behind can be done, but here is how I do it. Tap her very slightly on the shoulder with the tinest of taps, like you are a mouse. Then move back a bit. When she turns around, act like you are moving backwards. Act apologetic and act as if you are the most harmless thing on Earth. Smile. Might go over.
Watch the entire interaction like a hawk, watching her every move and analyzing everything. When she gives you, "I can't believe you're even talking to me, you reject!" look then just walk away very rudely and leave the cunt hanging. Be as mean to her as she was to you.
