When writing a business letter, the writer must have a good sense of humour which show that he is capable.?

While having a good sense of humor can certainly make a business letter more engaging and enjoyable to read, it is not necessarily a requirement for demonstrating capability. The most important aspects of a business letter are clarity, professionalism, and effectiveness in conveying the intended message. A well-written letter that is clear, concise, and to the point will always be more effective than one that relies solely on humor. That being said, a touch of humor can help to lighten the tone and make the letter more memorable, as long as it is appropriate for the context and audience. Ultimately, the key to writing a successful business letter is to strike the right balance between professionalism and personality.
