B. “You can’t deny laughter; when it comes it plops down in your favorite chair and stays as long as it wants.”

C. “You would have thought that somewhere in the last 12 years they would have taught us how to say goodbye.” OR “You’d think that somewhere in the last 12 years they would have taught us how to say goodbye.”

D. “Success is to be measured not so much by the position that one has reached in life as by the obstacles which he has overcome.” – Booker T. Washington

G. "Never mistake knowledge for wisdom. One helps you make a living, the other helps you make a life." - Sandra Carey
