  You can babysit by the time you're eleven or twelve.

  You have one regular computer and four to six laptops.

  You just know when your mom is pregnant before anyone else tells you.

  You clean the whole house every day.

  It's hard to agree on what music to listen to, 'cause everyone likes something different.

  You don't get your birthday meal with Dad because there's always someone in line before you.

  You celebrate three or four birthdays in less than two weeks at least twice a year.

 You can't agree on what to play because everyone wants to play something different.
