Why asking my address?

A friend of mine who lives in another state asked for my home address because she said that she’ll send me some christmas cards. I don’t really know the true reason of her asking for my home address but I gave it to her anyways. Well, she knows that we don’t really participate in such holidays because of religious reasons, so I doubted her sending me one of those said cards. I think the real reason why she wants to know where exactly I live is because she wants to surprise me one day with her knocking on our door. It would be nice to see her visiting me here in San Diego so we can be updated with our precious life. Wink!
