First, let's see a video below and guess what happen really!
"Show your English， ok？ Where （are） you from？ "
"I don‘t f*** care. I only care （about） you。"
"Get out of here！ Get f*** out of here！ "
"Talk to my （me in） English！ Come on！”
Then the man said “your make a grammatical mistake”
Where （are） you from？
“I’m from the US。”
“I‘m from the US， too！”
So, just another elder without manners wanted to get a seat in metro, and has conflict with another man?
No!
In fact, the elder is a good man, and the young guy is a good man, too! So, what was really happening?
A pregnant woman( about nine months) got on the metro, and the elder wanted to give a seat to her. However, she refused, because she thought the elder should have a rest also.
Then the elder asked a girl opposite to give a her seat to pregnant woman, and the girl was willing help them.
At that time, a young man saw and thought the elder man was forcing the girl to give a seat. He decided to "help" the girl.
The conflict broken out!
Because a misunderstanding, two good men were squabbling. 
Now these they should have known the truth. LoL!
