You mean you had a little arguement with your mom in front of your friend?
It's a little bit complicated.
First, he a little bit was annoyed by the way I talk. I really talk bluntly. He used to accept it, but he once complained it because he was not in a good mood.
that was a start. but it was not a main deal.
Actually there has been a girl whom he likes. ( I know this girl also) They both hang around all the time (it's just not hanging out, they take the same classes together, study together and even stay up all night together. It's been about 2 years now) But everytime he asked her to go out, she declined. But she wants to keep him just as a friend. Well he's kind of timid boy and he thinks only the way he can be with her is be with her that way. So they are still hanging around with each other even though his mind is not the same of hers.
And one time there's a sort of mistake from her and other classmates were joking about it. But he defended her. So I gave him a bitter comment. Then the fight started.
Well at that time I realised he's a such a loser. That's why I'm really pity for him. Actually he's not a bad person, but he's a loser. Maybe he thinks the fight between him and me is not related to the girl he likes. But it's obvious when it is looked closer.
