alright just wondering how to take these two to the next level...

met this chick at hot topic while i was buying something for a party.. i invited them to the party and she got my number.. she ended up calling and all in all i ended up smashin that girl... but i dont really want her im looking at her friend.. who at that party asked specifically for my number and said we should " chill " i can see this getting a little complicated and am wondering in what ways to move on from her to her friend without losing a chance to get her.

secondly i got a girl coming to one of my dance workshops tommorow.. anybody got any good ideas of what i can run after its done there?

If you want the other girl, than you just need to go for her. Be honest and upfront, and if it doesn't work out then you bounce back to the other girl. There's no "good way" to handle this situation beyond going for what you want.

As to the girl at your dance workshop. Just chat her up when its done.....there is no magic bullet to getting her. Think about this: you just got done doing a dance session together, you already have SOMETHING to talk about. Start talking and before you part ways get her number. Simple.
