More and more

I am still learning more and more things about my sister. It makes me sad that I am finding all these things about her from other people. I am finding out things about her from the things people do because of her. It kind of makes me question if I spend enough time getting to know the people I love.
It seems odd that the closer you get to a complete "picture" of a loved one, the more you miss them when they are no longer around or out of sight. Is that because you know that there are still pieces missing?
