10. It will make for an even more interesting storyline
It used to be that when a TV couple finally made it official, the joy of their relationship would evaporate along with the sexual tension. But TV writers have worked around that in recent years, proving it can be even more exciting when a couple stops dancing around their mutual attraction and gets down to business. On The Office, Jim and Pam spent years teasing fans with their will-they/won't-they flirtation before hooking up. They dated other people, almost got together, backed off, and then reunited — just like normal people. When the writers finally opted to give them a happy ending, the show didn't lose its luster: First they tried to hide their relationship from their coworkers, then they got married, and then Pam found out she was preggers and popped out a mini Halpert. When two characters start dating, the 'ship can spawn entire seasons worth of new material.
