Wanted to ask you all if you have any advice on how to handle silent rejections.

I've been working on improving my confidence and have been approaching random girls at bars/clubs. Usually the conversations start fine and we flirt, etc...

Several times, however, I've approached a girl and she straight up says nothing and ignores me like I don't even exist and walks away or talks to her friends. I usually approach by just being friendly or saying something about the venue so it's not because I'm being crude.

It amazes me that some people are so rude that they will act like you don't even exist. To me, it's a pretty brutal rejection and embarrassing if others see. (But who cares I guess)

What I've been doing lately is just pause, smile and laugh at the situation and then continue to go on with my night. It's kinda hard to recover quickly sometimes though.

Any advice on how to handle this? Thanks!
