Punctuality is a good habit. It means to do things at the fixed time. When others are late and you have waited for a long time,you must be angry. And then you should try to be punctual. So you will win others trust. At the same time if you are always not punctual, you will become lazier and lazier, even fail in the life.
No punctuality is a bad habit. We should get rid of it. We should try to be punctual forever.
