Why do we...

Why is it that we are different people when we're with different people? Do the people that we think we are the closest to even know the real us? Do we even know the real them? How can a married couple get divorced after 20 years citing that they never knew each other? Why aren't we still friends with people we grew up with, but couldn't have imagined life without them then? Maybe the people who only meet us once really know us because we never had time to show them we're someone we're not. Why does it come so naturally? I'm not the same person with my boss as I am with my grandma, but I don't lie to either of them. What does this say about us as people? As friends? As grandchildren?
