Do we REALLY know another?

Do we really get to know another human being? Do we? I mean, REALLY! Even married couples say that they don't really know their spouse. Is our life so busy that we don't even know our spouse? Or our family, or friends, or associates, or... the list goes on. This great internet thing- is it a help or a hindrance to real communication? Some serious questions to ponder. I am going to visit my mom- I REALLY know her! Then I am going to call my children, I believe I REALLY know them! The reason is that my mom raised me, and I raised my children- maybe they are the ONLY ones I REALLY know, but at least I know that! I know that I know that I know! Know what I mean?
