My little sister and her daughter are so much alike myself and my daughter, and we can relate in a lot of things. Seeing my little niece grow up has been an amazing journey, that I'm now reliving through my own daughter. Our relationships, mothers and daughters, remind me of a quote from the Louis CK show, which goes something like this:
"Because of these children, our love travels through time. We love other people more, because of how much we love them. They give value to our lives that didn't exist before."
