Don't come near my Granny Smith Apple

I have a true love for Granny Smith Apples. I can eat those all day long but not red apples. I'm not a fan of red apples. Anyways it is very obvious that Tegan shares my love for these apples. He couldn't figure out how to take a bite out of it but wouldn't let me help. I mean he screamed bloody murder every time I came anywhere near him!
