OK so just a simple question.

I met a girl really briefly, basically just numbers very little conversation. Shes young, 17, and so am I. Now she is happy to meet me but she wants to bring a friend and suggested I bring one as well. Im not sure thats something I want to do.

Should I tell her I just want to see her or should a bring an inexsperienced friend along? Is two girls and me a bad situation?
