For the longest time, Bing's only friend was his sister -- she would tell him that his other friends only liked him for their money so often that he began to believe it. That is, until Darcy came along; he could be a little overbearing at times, but he was loyal, and fun to be around. He took Bing under his wing, showing him what a true friend was like, taking charge of things in a sort of comfortable familiarity; it was okay, though, he knew how to follow a lead.
