From our favorite former Ithacan:
Teacher: "Tomorrow is picture day. Be sure to look your best. Here is my class picture from when I was in first grade."
Smartest kid in class: "That's funny - you're white."
Me: "Of course I was white when I was 6 - I'm white now."
Smartest kid in class: "But now you're a teacher. Plenty of teachers are white. I didn't know kids could be white too."
