"I'm Caucasian and my kids' father is Mexican so they have a Spanish last name. Well, I went to my son's school for the first time for his parent-teacher conference, and there was a random stranger of Spanish descent sitting at the table with us. When the teachers started talking, they directed everything they said to her. That's when I realized she was an INTERPRETER! Their faces couldn't have been more red than when I told them I understand English perfectly!"
