The most amazing person you could ever meet. She has every single positive trait you could possibly think of and she makes you feel happier than absolutely anything in all of existence. You are thankful to have her in your life and everybody loves her, especially people named Ethan who loves her the most. She is so special and you would do anything for her. I love you Jaymay
