like the same way.when she asked me that wher i get her number,then my answer-
"yesterday night some of my frnd come in my room and we all are doing gossip,when they went from my room i just noticed that there is a 1 dialed number in my mobile,so i'm confused that who dialed this ,Thats why i'm calling you to know that who r u"
after that i asked here.that where it is.then she will give some answer like the place name,suddenly i told her that in ur place one of my frnd home there.may be he dialed ur number.ok i have to ask him,next i asked so what is ur name.
i think that's enough.
