But you shouldn't make the mistake of forgiving everything, just as you shouldn't tell your children that they do everything great even though it's "only" average or bad. Nowadays, it is also a fact that the economic interests of entrepreneurs sometimes lead to poor performance or an overestimation of their own capabilities.
Objective criticism, including of unfulfilled promises, must therefore also take place as part of a self-assessment of the company's performance. There is the salesperson who promises and the technician or developer who then has to deal with the problem of meeting the deadline and often enough the technician has the disadvantage or the product then has the fault.
In this case, one should be understanding, but forgiveness is a little much to ask.
