Do you have friends who seldom smile to you when you meet? Well, don't blame them for not smiling to you. Try to smile first at them. If you do this, they will probably smile at you. If they don't, try again next time. Smiling will make your life happier and people around you will find that you are friendly. This is important when you want to pass your day whether at work or at home. If you put on a gloomy face, people around you will get far from you. You'll be lonely all time. Sometimes, you don't have to say anything if you don't know what to say, but give a warm smile will be a good response to others.
