Super Junior Beautiful smiles

All of them have such amazing smiles. I am sure they experience bad things but when they experience good things and smile like this they brighten the world. I had a teacher once, she was very kind and young. She was the nicest teacher I ever had and she would always smile. Someone once asked why she smiled so much, her response was: "What reason do I have not to smile? Smiling makes the world brighter. When things are sad try to smile. It makes people happy to see smiles. All of you have beautiful smiles, share it with the world." I remember her words whenever I am sad, she is the best teacher I ever had and I think people should follow her advice.
