1. About Clothes
    Advantage: when they're older you can share clothes. Disadvantage: your clothes disappear because they borrow without asking and can't ever remember to return stuff.
  2. When Your monthly cycles eventually sync up
    Disadvantage: exorcist times three. Advantage: we pretty much get whatever the hell we want for 3-5 days.
  3. About Disney Princesses
    Advantage: Those sweet ages when it's all princesses. All the time. Disadvantage: When they move on to this Descendants bullshit.
  4. Seeing yourself
    Disadvantage: You're often reminded of the foolish mistakes you made in the years just ahead of where they are now. Advantage: You're reminded of second chances in the way you raise them to hopefully make better decisions.
