Which of these words best describes the tone of the following excerpt? Each of you is signing up to be the moms and dads of hundreds, maybe thousands of kids over your career, and you will love those kids like your own, and they will all carry big pieces of your heart with them wherever they go, and some of them will break your heart. You will go to funerals as well as graduations, you will go to court dates as well as parent teacher conferences, you will go to rehab centers as well as weddings. And at that moment when your heart is the most broken, at that moment, they will need you to love them the most.
