安全感就是能在小汽车的后座上睡觉。小时候，爸妈开车带你出门，到了晚上，你不知不觉在后座上睡着了……你啥都不用担心，爸妈就在前座上，他们负责忧虑一切……但是这样的时间很短暂，一不小心你就变成了那个坐在前面的成年人，而成年人永远失去了在后座睡觉的权利。

Security is sleeping in the back seat of the car...When you're a little kid, and you've ben somewhere with your Mom and Dad, and it's night, and you're riding home in the car, you can sleep in the back seat...You don't have to worry about anything...Your Mom and Dad are in the front seat, and they do all the worrying...But it doesn't last! Suddenly, you're grown up, and it can never be that way again!
