Birthday

Birthdays occur when Sims go to their next stage of life, which can be one of the following:


 * Baby > Toddler
 * Toddler > Child
 * Child > Teen
 * Teen > Young Adult (requires University)
 * Young Adult > Adult (requires University)
 * Teen > Adult (Note: This occurs when a Teen doesn't go off to a University Neighborhood)
 * Adult > Elder
 * Elder > Death

When a Sim's birthday is within two (2) days, text will pop up on the screen saying, "Your Sim's Birthday is only 2 days away! You can have a birthday party. For your sim to have a birthday party click the phone and go to throw party - birthday party." Birthday parties are only available if a Sim's birthday is within two (2) days. For the Sim to grow up there must be a birthday cake present. If the sim is a Baby or Toddler then an adult will bring them to the birthday cake in order to grow up. Otherwise the Sim will walk up to the birthday cake in order to blow out the candles, when they do this as an autonomous reaction Sims around the birthday sim will watch that sim blow out the candles.

Even though it is possible for Sims to have birthday parties they don't need to have them in order to grow up. Once their life stage meter is full at 18:00 they will grow up automatically.

Every sim that grows up to a new stage will acquire a new memory depending on their aspiration at the time, they can have a bad or good memory.
