Let me try to explain it this way. There's 2 reasons a person becomes a mentor.
1. To help a newbie be successful and self reliant. To do this, the mentor gives the mentee all their resources, and how to use them, so they can go and find the items and info they want in the future.
2. To make the mentor feel good and important. In this case, the mentor goes to their sources and gets the items and info, and takes it to the mentee. It helps the mentee that day and makes the mentor feel good and important. It doesn't help the mentee at all in the future. We are here to teach the mentee to be self sufficient, not just to help them today. Therefore, we guide them to the source of the answers they need, not "just" give them the answer for today.
