How long will you wait? Especially when it is important you should try to get it done. Those that you are waiting on may not even know that you need it done right away unless you tell them. If you don't tell them they will assume you are choosing to wait. Whether it is an appointment or answers to questions you need right away don't keep waiting just let them know you need it and you won't have to wait so long. People don't know what you need unless you tell them.
