Do you want preteens or not *Note* (I do respect everyone opinion)

By all means. Let us get some awkward pre-teens, with some extra struggles added to them. Their first crush, arguing with parents and playing with friends long into the night until either said friend's parents comes to retrieve them (a Sim with child hater trait rarely bothers, and is always angry) or your teenage Sim's own parents finally get a proper usage for that Werewolf dungeon in the basement.

Current teens always feels like they're at the end of their lifestage. College, getting a job, essentially doing everything the young adult does, sans proper jobs and pregnancy. Pre-teens should be about having fun and enjoying life before it's time to become a young young adult older teen. They can improve the older teen while they're at it.
