It's all in the name!

Mariella received a thank you card from her friend Sophia for going to her birthday party and for her gift. Sophia signed her name on the card and Mariella was reading it and all of a sudden looked shocked and said, "MOM! Sophia spelled her name wrong, she forgot the "F"". So I laughed and tried to explain how "PH" sounds like "F"... Mariella looks at me, puts her hand on her hip and says, "Does she speak Spanish or what?" !!!!!!!
