You can do more than clicking a 'like' In this picture,a cadger in shabby cloths with his child to beging. A person leave a 'like' in his worn bowl. Does the cadger only needs a 'like'? Evidently he doesn't,What the cadger need is food and money,he want to ensure he and his little son can live without anxiety of food and money. And what does a 'like' mean? With the developing of SNS,'like'had another meaning,it means "I know it",and just means 'I know it' , that's all. People won't feel comfortable when you give them a 'like'. If one day,your friend was in trouble ,he wanted your help,but you just leaved a 'like'to him,how disappointed! Furthermore,concerning our environmental pollution or other social problems,you can't just click a 'like'. You can forward some news to appeal more people to pay attention to these problems,or you can do something try to be help. Anyway,you need to remember that you can do more than clicking a 'like'
