Well, "gross" does also mean "total", "whole" and "entire".
We're a needy race. We always have one craving or another and there are tons of things the world has to offer that can satisfy the need for a moment or two. Then we overdo it and those things suffocate us. It just gets way more emotional when people use other people to fill up the emptiness. Eventually someone smothers someone or the one finds that the other isn't enough (because on top of being needy we also can become quite discontent quickly). It does make one rather cynical when one expects fulfillment from other humans, doesn't it? Even sharks have no use for them because they apparently taste bad.
However, in the grand scheme of things, we probably will see that we must do our best for each other and help those who are down look up rather than look to us. Otherwise, you may end up with a stalker.
