hello
from what it sounds like you did rather good, smart idea to tell her to talk on the intercom its creative which is always great (to many people talk about things that are boring.)
here is some Q&A
1- me and my wing do switch who opens. i tend to be better at straight openers, i think fast and dont need canned lines, and my wing doesnt do so good thinkin quickly. but when we open he is good and keeping a convo, we bounce subjects off each other while talking to people. i suggest you switch it up to practice opening. it isnt the most important thing in the world but if you cannot do it at all you wont get the chance to succeed.
2-depending on what you are doing this can be a big factor or not. if you like to directly approach, as in open with a compliment and something funny there is no reason to feel like that. in fact that tends to work. but if its a hotter girl and you feel that you should approach indirectly, just be funny, use a neg and keep a good frame. you have nothing to worry about most girls love when guys talk to them, seriously. ive even had friends who are girls say to me "ethan..sometimes i just wish a guy would come up and talk to me, and be straight forward and just be real, even if i don't know him and he just is down to earth and sweet. i would love that

" and that comment came from one of my best freinds who is an HB9.5. girls wont shut you down as often as you think!
3-yea, not the greatest but its ok its only your first time and one time. keep that in mind, when you cold approach it is only one person, outa the few billion women in the world. keep cool, good eye contact, smile, just be casual and relaxed. along these lines, maybe wear something a litte better looking. no offense to a hoodie but if you look presentable girls take more interest in that. just something to keep in mind
4- number closes, are not closes in my mind. they are leading into day 2s. thats it hands down. so, when you feel like a girl who is really cute that you open and wanna get her number, just remember that this is to k close or go on a day 2 with if you already havnt. a number by its self is pointless unless you proceed with taking it to the next level. as for how to number close, its really simple. DONT do it randomly, like you said. you are right that will be creepy ha thats not a good way to. there are various fun little ways to do it here are 2 examples
Ex1
"hey so i gotta go right now, but you seem like a cool girl (crazy, fun, any word to describe how she acts) whats a good way to keep in touch?" see how this is not "random" but more subtle, still direct tho.
Ex2
"can i barrow your cell phone for a second? trust me only be a quick call" get her phone and put in your number. then make sure you just call your phone so you have the number too. and say anything after like "well you should text me later i will be (having a party going out to eat ect ect)" then just say "had a great time i gotta go tho, il be waiting on that text" later on maybe she will text you if you put in your number, if she doenst notice just text or call her the next day act funny and just say "never waited so long for a text! anyways stranger we should hang out again..blah blah blah" and just go from there. these are kinda basic ways, but for a number thats all it takes, no need to make it to hard to do you know what i mean?
best way to learn is to go out and practice, just be talkative with anybody not just good looking women. this will keep you in a talkative good mind set and help you as you talk to girls and sarge more
good luck mate
