Another one gone, again

Rico says his oldest friend went through another series of phone calls and voicemails (all unanswered by Rico), and even descended to pleading emails, also not responded to. It's like listening to your dog howling to be let in, and ignoring it; hard to do but, alas, necessary. This one has the tendency to sucker Rico into thinking things are fine, then turning on him, savagely, and Rico is not going to give him the opportunity to do it again...
