Guy's Behavior

I can't forget this incident? An old event? Why does a man do this?

I said hi to him how are you doing?
He told me it doesn't matter.
I said what your name is Suddenly, the bell rang
He said time was running out
He said you'll try again next time
And he looked me in the face and laughed. And he walked away quickly.
Why do men do this
But the boy is very handsome And one of the smartest in the school Doesn't use social media at all He didn't say anything about his life. Why does a man do this?
