I find myself wondering... At what age do people usually realize that "soulbonding" and having a bunch of fictional characters living in you is a phenomenal load of horseshit? I don't think I've seen a soulbonder past the early 20s (but I'm sure there are a few 30-some moms out there who believe Snape is helping them rear their children). I guess the concept of imaginary friends gets appealing again around high school/college when you have to start accepting adult responsibilities.
