The idiom “As you sow, so shall you reap” means that the way a person behaves with others will determine how others will behave toward him. If a person has good thoughts about others, he will have everyone’s trust and if a person has negative thoughts about others, other people will never talk to him and he will be left alone.In short, if you do good to others you will also be rewarded with good and if you are bad or unkind, you will get the same from others.
