There are only two place you can blast your music loudly.
The first is in your house, the next is in your personal
concert.
It seems like public transport is neither of them. You should be
glad that it's that elder that chided you. If the person who chide
you is me, you will be in a lot more.
Any barbaric actions by a barbarian is beyond my comprehen. I can't
think of an excuse for these barbaric act with my simple mind.
Sorry, I can't give you any defense.
When others ask you "Where are you from?", please tell them
anywhere but the country you from, schools you are studying / had
studied before, your surname, your race, your dialect.
Congratulations, because you have just disgraced the above
mentioned.
