Look at the mother's face. You can see she is doing her best, and the best thing for herself, in thinking of the happy times, under great strain. Don't think I'd be facing any cameras if that were my daughter but it may be the best thing to do in grieving, telling everyone you can just how good and happy the girl was, how much she brightened your life.
Everybody grieves in different ways, That's their "public" face what they're like hen they're alone or with the family is another matter. What ever, I'm sure our sympathy is with them.
