I actually miss being able to play as both pets and newborns. But that aside, the first time I played Sims, I kind of wish I'd known beforehand that the "Woohoo" interaction was really kind of SFW instead of NSFW. I mean, it's really just babbling, giggling, rose petals, moving bed covers and a snippet of music or two. That's it. Knowing that beforehand would have saved me a lot of embarrassment.
