Cheaters are more likely to suspect their spouses/partners of cheating or be suspicious that it might happen. Ask any counselor. You sort of screw yourself (pretty much literally) when you cheat. So don't, even if you're not in a relationship that you are thinking about for the longterm. Karma exists.
I just love the little ways Shaq expresses his utter contempt for KB with things like referring to him as "that guy". The evil part of me fantasizes Shaq taunting KB on the court, Kobe foolishly taking the bait and throwing a punch... and then finally being put out of his misery forever.
