We can enjoy a cup of hot tea made by our mother easily and warmly, but we often refuse a cup of roasted tea sent by our friends sitting next to us on the train. It is easy for us to believe friends' jokes, but we doubt strangers' suggestions. This is really a complicated world! Common scams are wantonly staged on the stage of life; Rumors and rumors make a stranger's face look sinister. We live in our own narrow world and dare not reach out and touch the outside world. We are even afraid of everything outside ... on a quiet night, you are walking alone on the path, and suddenly you see a strange shadow in front of you. He walks up to you and looks into your eyes-what does he want? Robbery, assault, even ... Has he been eyeing me for a long time? Was it a premeditated action? You want to panic, even unconsciously hold your hand into a fist to prevent a sudden attack-but he walked by without saying a word and melted into the night. You start to calm down, but you are still wondering if there is something else going on. ..... Tired, we are all tired, and forget the trust we once called for. Diaphragm and scruples make trust like a distant star, but we are out of reach. When you are struggling with a difficult problem, a classmate who is only a nodding acquaintance with you gently tells you the answer. You suspected that you looked into his eyes and there was goodwill and friendship in it, so you smiled with relief. And help you solve your doubts. You doubt, but you feel care and sincerity from his words and deeds, so thank you sincerely. In fact, many times, it is not others who give us doubts, but our own hearts that are suspicious because of vigilance; We should not be misunderstood because of unfamiliar feelings. In this complex world, it is a deep trust to treat others simply and simply. A cup of fragrant tea can taste the fragrance of trust. With a word of advice, you can appreciate the meaning of trust. It is human nature to trust relatives and friends, but it is a virtue to trust others. In the process of trust, you can know this seemingly complicated world happily and comprehensively.
