Alternatively – your friends will only turn 21 once – so get to their birthday celebrations with a ride-sharing service. If you have a car, you can offer seats to paying passengers, raking back a third of your petrol costs for each person you take on board.
或者这样说,你的朋友们都只有一次21岁,所以你可以通过拼车服务去参加他们的生日庆祝会。如果你有车,可以捎上愿意付钱的人,毕竟多一个人可以帮你节省三分之一的油费。
