I've been invited in to witness and document the most emotional and vulnerable moments in peoples' lives, received hugs that almost hurt in their intensity, cried at a lot of weddings where I barely knew anyone, given piggyback rides and hugs and camera lessons to many adorable children, and most of all, become a much better person because of all of this.  It's love.  Not just between the bride and groom and their families and friends, but connection and caring and taking care of someone because you want them to be able to remember this.  Forever...
