The town I live in is about to put cameras at all traffic lights to catch people who run red lights. It 1 me of how many people I’ve seen who take the yellow light as a 2 to go faster. I also can’t understand why people don’t move when the traffic light has turned green. Above all, there are those 3 situations in which someone doesn’t even 4 that the light turns red, and just keeps going. That is why so many 5 happen! All these situations make me 6 the purpose of traffic lights.

So I guess I do like the idea of a system to 9 traffic. And I’ll do my best to 10 the traffic rules: to go, to be cautious, and to stop when I’m 11 to.
It occurs to me that my 12 have done much the same for me 13 teaching me how to live. They have given me many 14 lights: to get along well with others, to listen and talk to them, to help others, and to 15 with joy and purpose.
