There is no common topic between boys and girls. If there is it
would be boring topic.
Unless you are an entertainer, do not try to entertain the
girls. You'll be the clown of the party.
Just keep quiet for starters, let the organisers of the
orientation do their job. Don't look worried, neither grin
permanently. Just look relaxed. Consciously relax the facial
muscles, with just a slightest smile.
Don't think of performing well, just look, and see what to talk
about there and then. Like Name: "that an interesting name,
does it have any meaning?" Fashion Accessories: "thats an
unsual bangle, is it tribal?" Anything there.
Get her to talk about herself. You listen, talk little, and then
ask question about her opinion, what she thinks about ....,
how would she.....
Never go into negative expression, express in the positive, i.e
that is good, thats very nice, its ok but I don't like it.
Avoid saying "its the worst shit I ever saw" even if it is
true. "It could have been better", would be better said
Remember she may also be a noob. She might also read this,
and ask you questions. Answer plainly, positively, and throw back a
question. Never criticise her opinion, but just say you agree or
don't agree, and give praise where it is due.
Don't prepare for a good encounter, all that I tell you above
will go to blazers when a pretty girl smile and say "Hi"
to you.
