"If you treat people right they will treat you right... ninety percent of the time"

Franklin D. Roosevelt's quote is a pointer that how we deal with others is often shown back to us. He suggests that if we deal with people with respect and kindness, they will generally react in kind. He likewise implies that this is not always the case, as he specifies that it will take place "ninety percent of the time". This recommends that there is an opportunity that our good intents might not be reciprocated, and that we must be prepared for this. Eventually, Roosevelt's quote motivates us to be kind and comprehending to others, as it is likely that we will get the exact same in return.
