想想这个社区的其他服务人员。我们有收集垃圾的人，他们负责保持社区卫生；我们有道路工人，他们竖起、修理交通标志牌，维修道路，不仅保护着我们自己，也保护着我们的汽车！

Think about all the other service workers we have in this community. We have people who collect waste and rubbish and keep our community sanitary. We have road workers who put up and repair traffic signs and fix holes in the streets to protect not just us, but our cars!
