Nearly 100 percent of female prairie voles who had partaken in the ethanol festivities, they found, preferred interacting with their partner in crime rather than the new guy. In contrast, two-thirds of the sober females liked their overnight partners best, but the others did not care one way or the other or else liked the stranger better. Males were a different story, doing just the opposite. Upon being reunited, the soused males oftentimes shunned their prior paramours, instead tending to show significant interest in the intriguing new strangers they were introduced to. The sober guys, on the other hand, were hopeless romantics. All of them preferred their original partner to the stranger.
