If an old man suddenly falls down in front of you, will you help him? Most of us would choose to help him we know it's the right thing to do. But others might refuse (do) so. In my opinion, we should not only think about (we) but others as well.
I've had an experience like this before. I saw a woman walking with a baby in her arms while it (rain) heavily. They were both wet because they don't have umbrella. I held out my umbrella for them (quick) I walked several miles with them till they got home. The woman thanked me a lot for I did for her. At that moment, I had such a strong feeling of satisfaction. Offering help to people trouble can make them feel really warm. And perhaps one day we'll because the one who needs help. So why don't we just reach out a helpful hand whenever we can. The more we trust and help each other, the (good) our world will be.
It's a high time for us to show our (kind) to others.
