im gona have to say go with it. but home phone number's aren't typicly what i want to get..
first, any one can awnser, And let you know their not home. when their quitly listening LOL..
but i wouldn't let it discurage you unless her body laguage changes or, you try to call back again and get her family again. <- at this point i think she was being nice, and couldn't think of any other number to truthfully give you w/ out gettin shit from her friends.
i would definitly talk w/ her in person before tring to make a second phone call, you would look eager if you call again, plus if she did get the message w/ your number , it's not a good sign she hasn't called back & you bug her.
