sit near that person where she/he can hear your talking when you
are talking to another friend. If you do not want your friend to
find out your intention, you will have to really know what you are
doing. shift the conversation to the environment and hopefully you
get that person's attention. Comment of that person's environment.
Eg ( table, chair , light , shoe , branded good etc). Direct
conversation to handphone. If she takes out handphone ... close the
deal. ( ask her handphone model, price , where she bought).
