Some people really do want nothing else besides having the people around them laugh. They find a lot of solace in having the people around them laugh and all that matters to them is the fact that they have made the people around them happy. They are even willing to take a joke on themselves, if that guarantees the happiness of the people around them. This woman wanted this to happen, which is why she posted this snap.
In this snap she can be seen like she is stopping someone else from taking a photo, but by willingly standing in front of a mirror, she is letting her friends know that she really isn't with anyone else, but is being creative by herself in front of the camera. This is one next level funny person here and she deserves a medal for sure.
