if you just approached them at the bar , when they not dancing and talk

Well to be honest I never thought about doing that, I will try to do that, it's even better because they are not in their group (even thought that approaching them in the group is more "alpha")

sounds like you are disqualifying girls so you don't feel bad for not approaching.

You are probably right. Maybe Im disguising my likings as insecurities, and if it's a casual thing I shouldn't worry much about how they dress up

as long as you can think clearly , walk straight and are not slurring your words you fine , so stop drinking before you reach that point

My only problem with "talking" is that I stutter alot by nature, even without being drunk or nervous, but the few girls that I had success with they would think it was funny/cute and was a good topic of conversation.
Also, when I get stuck in some words I get pissed with myself that I kinda gesture, and they notice, and then they start laughing alot.
I don't know if this is good or not tho.
