I have two questions:
1.If a girl I don't know so good or I have talked to here only a few words, always greets me if I see her, ist this an IOI or has she only a nice character?
2.I was in a club and two girls asked me if I have a cigarette. THen they said that they know my sister and we talked a bit.
Question: They came to me because they would smoking or because they would talking (and be seduced

)
I know this are simple questions but im not sure about them, I think it depents if they would be seduced or if they only would be nice.
Need opinions,help please, thanks
