The same is the case with us also. We may seek different information from different people. We will inform them. But we'll start following up with the person from whom we require information immediately.
Yesterday I was making a presentation on a subject for one of my customers. I asked him for some information 4 days ago. But I have not received it. I waited and yesterday I called him and asked him to send the information immediately. 4 days I waited as I have no urgency but yesterday I followed up with him as I want that information to complete my work.

Now, another point the author has raised is about need. If we are capable enough to fulfil the need of anybody whether it's inside or outside an office, we should not refrain from coming forward to fulfil need of other people. However, as the author has written that some people may object on us for not fulfilling their needs. I think morally nobody has right to demand us to get his need get fulfilled because it is entirely on our choice whether or not we fulfil his need or not.
