Sneak out

Teens in The Sims 2 can choose to sneak out after curfew without permission. This action is available on the phone from 10:00 PM to 1:00 AM. To have a Sim Sneak Out, click on a phone and choose "Call...Sim....Sneak Out", then the Sim will be asked with which teen they would like to go and if accepted a message will appear on the upper-right corner with the selected teen Sim saying "Cool! I'll pick you up at 1 AM." If rejected a card will pop up saying "(Sim Name) doesn't feel like going out right now." When the car arrives, the Sim will tip-toe to the car and will be out from 1AM until 4AM.

If the Sim is seen, an Adult Sim will run to the teen and lecture her/him, telling her/him to go to bed. The car will leave, and the teen is forced to go to bed or be "chastised." When a Sim refuses to go to bed, they will be followed until they receive a slap in the face. Teens can also be caught by the police when they're out of the house, who will promptly send them home in the back seat of a squad car.

Teens that successfully sneak out get a positive memory of it, while teens who are either caught sneaking out of the house or caught by the police will get a negative memory of it.
