Dear @chbartist sir!
Sometimes, if we say no promptly, we become a victim of mental depression. I would like to give an example of an insurance agent. If you are not willing to take insurance policy then do not say in clear terms. If there is a slight downside, then the insurance agent has so many ways to explain that they will accept you by doing yes. If we are not able to help someone, we should not say immediately in clear words. After saying this, it has to face a lot of trouble because of the deficit.
Sometimes, due to the over-busyness, this platform has to say no to it.
