Bride
She'll ask you to explain what's going on in a movie then turn around and tell you about tiny intricate parts of each muscle in your body.
Groom
He could argue with a brick wall and somehow still believe he won.
Best Man
He might have access to google but that won't stop him from asking you instead. The worst thing he can do is get something wrong.
Maid of Honor
She’ll bake you something amazing, randomly start dancing… and end up with another broken bone.
