Thank You, Mom

Motherhood has changed me in a lot of ways; one of which being that I cry more often and am a sensitive little sap.  This commercial brought it on, full force.  They've been airing the shorter version on NBC throughout the Sochi Olympics, and this one is even better (or worse, depending on how you look at it).  I was initially bugged by the lack of racial and ethnic diversity, but I then I googled this next one, and it was all over...the resentment as well as the ability to hold back more tears.  Who am I?!
