Manners - It's a very important topic, and in a healthy and professional network, it's very important to behave with manners. In society, it has been observed some people knowingly or unknowingly send bad post text, which is not good for owners. A small example like a 35-40 Age person call a 65+ year person by name. This looks very small and simple, but it disrespects the senior person. A person who needs to read the basics and speak to discuss advanced topics is something like a child who is not qualified for middle school is asking for a certificate of senior secondary school.
