Best way to approach a girl when shes with family members or friends?

[gbasource]

Whenever i see a girl I like theyre always with there mom. brothers or friends. Hows the best way to approach her without making any of them mad? And what stuff should i say?

Maybe wait for the girl to get up when she moves away from the other people, or try to sit at the same table and maybe smile at her, to indicate that your interested.

I thnk its best to get her when she is on her own, at the bar, or when she gets up.
