Sometimes It Just Doesn't Make Sense

Thinking about a fellow IF blogger who's going through her fourth miscarriage.  She recently announced her pregnancy, and I was so hoping this was it for her.  I can only imagine how heartbroken she is tonight.  Why do some people have to go through so much pain and disappointment?  I wish I had the words to encourage her.  Some things I just don't think we'll understand this side of heaven.
