When I was in middle school, my home was about five kilometers away from school. Will I be laughed at if I don't go to school by car?

I have carefully read your question, and my suggestions are as follows:

First of all, 5 kilometers is still a long distance. For a middle school student, if you don't walk to school by bus at a constant speed, it will take about 1 hour if the road conditions are good. So we should grasp the time and get to school on time.

If you walk to school instead of taking a bus, generally speaking, your classmates won't laugh at you. Because, in a class, there are always people walking to school, which is not a shameful thing. So students won't care too much about it. Therefore, there is no need to think about it, just take part in sports and exercise.

I hope my answer can help you and make you satisfied.
