final farewell

From that day on, there was no more dad waiting for him after get off work at the window.
Dad never came back with Eggman.
Dad... will never come back.

When school was over, the little zebra saw the little tiger and shouted:
"Why don't you go to school? Didn't you do your homework?"
The little tiger often missed his homework, and the crocodile teacher always scolded him:
"You want to piss me off to death, don't you?"
The little tiger felt uncomfortable and scared...
Is it because of this that dad is so angry that he dies?
