My favorite invention is the bus. It is so useful because it helps me leave home so that I can go to school. The bus also helps me travel around the city so that I can see interesting places. I also use the bus when I want to visit my friends.
I like the bus because it is cheap. People should always be careful when talking to strangers, but I have met some really kind people on the bus. One woman helped me find my stop the first time I rode the bus.
