Some think we should try to help strangers． Helping others is a virtue，and helping others is helping ourselves．We may come across some trouble and need others' help some day．If everyone isn't willing to help us just because we are strangers to them，it's hard to imagine what our world will be like．
However，some are afraid that helping others can sometimes bring us trouble．Sometimes we are just misunderstood and even have to pay the cost of kindness．
In my opinion，we should try our best to help others when they are in need of help，but we should also protect ourselves from getting into trouble．If everyone tries a little kindness，our world will be full of love．
