i agree to the direct ones above,u want to talk with her friend so,that's what ur looking for,u don't wanna be having a conversation with both of them,so u gotta make it clear
to them that that's what ur looking for,so go direct with something like this,
Hello,I noticed u sitting down together(or whatever they are or doing) and i had
to come meet ur friend cause she's incredibly cute(or whatever compliment u want)
and then u wait for her response,her saying thank u,if u give the compliment correctly
then she'll just say thank u, after that u ask for permission from her friend for u
2 to have a conversation like this :
"do u mind if i chat with ur friend for a couple of minutes?" and of course this is not
up to that girl,it's up to if the girl ur interested in wants to,so the other girl will
usually say "sure go ahead,if that's what she wants"
this way,u made it ok for her to leave her friend for a bit and talk with u,
this way,so she'll feel ok with having a walk with u,or sitting together a bit to the side
hope that helped
