An old story of merchants tells about the case of a businessman who started an enterprise asking money from a friend, but the project lacked consistency, and he could not repay him. Filled with optimism, he decided to defer the loan with a promissory note. On the expiry of the document, he decided to change the note for a post-dated check of his wife, forging her signature. Upon expiration of the check, the friend, disillusioned, initiated a lawsuit. Then the debtor decided to fix the mess by killing him, but was discovered and imprisoned, as a result of which his family left him. Desperate, he ended up hanging himself with his belt. To cling to his own lies only worsened his bad decisions.
