At present we are living in a good age. Therefore, there are still a
small number of people who don't act responsibly. His bad behaviors are
out of place in our civilizing society. For an example, some people often
risk their lives to disobey traffic rules. Littering is still a seriously problem.
Some people are often seen spit in public places. Bad still, it is common to
find silly things written by some tourists in scenic spots.
To my opinion, everyone should learn to become a responsible citizen.
We must aware that everything we did in public places will affect others and
we should break our bad habits. As long as we obey the rule in every field and
are filled with care and love, our world will become better.
