So some of you might know the ' introduce me to your friend, thats the polite thing to do' gambit by mystery (I dont know if he invented it, but he teaches it.) Anyway, do you tell your target to introduce you to her friend ( lowering her value) or do you tell her friend to introduce you to her.

I don't think it matters, you do this though not when you open to a group, but when friends come in to the conversation (i.g. coming back from the bar with drinks) as to include them into the conversations.
