Giving free advice is a sad waste of effort. In the first place, no man will act upon it unless he is already inclined to do so. Secondly, when a man lays his case before you, the idea that he is asking your advice is a polite fabrication. He merely is suggesting that he is doing so, while as a fact his real object is to acquaint you with his personal activity. He wants to talk to somebody, being a natural gossip or gadder, and he plays upon your propensity for "giving advice" in order to get an audience.
