Wrinkles.

Brooke was looking at this picture. 

"That's not you and dad!"

Yes, it is. 

"No, it's not!"

Why? Dad doesn't look like himself? He looks different? Because I look about the same. 

"No you don't! You have wrinkles! Look, I can see them right here!" (Points to my forehead)

Me. Laughing. I guess it's true. I remember my mom being old when she was 36. I guess I'm old!
