This would be really great for the friendship page because it's a cute candid moment in a way. Maybe leave it black and white because it looks nice. It's also kind of an action/reaction shot which I really like and think would go well with our yearbook!
If you had a friend who spoke to you in the same way that you sometimes speak to yourself, how long would you allow that person to be your friend? The way you treat yourself sets the standard for others.
