Doubts and debts have different contextual meanings. Doubt is a qualitative attribute for uncertainty while debt is a money attribute which you owed or borrowed from somebody else. They have different meanings but sometimes they go together on certain situations. For instance, if you have doubts to a borrower, of course, you will not lend him your monies. On the other hand, a person with a habit of borrowing money to anyone else seems doubtful of his capacity to return the monies at the soonest possible time.
Some people who want to borrow money from you have a lot of drama in life or they pretend to be good borrowers. They will reach you out in many ways and give you many promises. But when they received the money and had granted their purpose, most of the time, they will disconnect themselves from you. Then, you will count not only months but years before they will return the money without interest. Unfortunately, some people sometimes never return the money to you for whatever reasons. Your hard-earned money had been used by others at their own sake. It is unlawful, abusive, and unfair practice. Thus, doubts and debts can destroy good relationships among families, friends, and colleagues today.
