“If by a "Liberal" they mean someone who looks ahead and not behind, someone who welcomes new ideas without rigid reactions, someone who cares about the welfare of the people — their health, their housing, their schools, their jobs, their civil rights, and their civil liberties — someone who believes we can break through the stalemate and suspicions that grip us in our policies abroad, if that is what they mean by a "Liberal," then I'm proud to say I'm a "Liberal."”

“I'd rather be nice to someone spoiled than mean to someone who really could use a hand.”

Context: We should not, certainly, punish other people in general because of an apparent lack of gratitude on the part of some. It could be that people are so busy they seem ungrateful — or they actually are thankless! But this is OK — I'd rather be nice to someone spoiled than mean to someone who really could use a hand.
