Expert’s Opinion: The pocket expert is usually right but the expert can be a little too precise when it comes down to showing interest in people and when it is time to do so.
The expert’s opinion is a subjective judgement and it is based on his/her experience, but it is definitely something that you can learn to appreciate.
