How to speak to a girl who is with her friends(girls & boys) whom i don't know??

I mean, suppose i'm close to a girl, but i dont know their friends, i feel offended when i see her and dont say hi or atleast smile at her because she's with so many of her other friends whom i dont know!! this has been my problem in life and people misunderstand me because of this, they think that i show too much of attitude and from the very next time they start ignoring me!! how do i overcome this problem.How to speak to a girl who is with her friends(girls %26amp; boys) whom i don't know??
well you can just say hi to her or something when she is with her friends, but try to catch her alone, and when ever you do don't skip out on that breif chance and ask her out or for her #How to speak to a girl who is with her friends(girls %26amp; boys) whom i don't know??
Well, it's polite to say ';Hello'; to everyone. She should introduce you, but if she doesn't, introduce yourself.
i mainly enjoy trapping my farts under my blanket, only to waft and engulf in the smell seconds later......
