Funny science :D

I learnt my science today.
Well, the teacher asked me, 'How do you separate the marble and flour?'
Then i said, 'Distillation.'
Teacher said again, ' No, you can't, you cannot make the flour again.'
I said: ' Ohhh, i see..'
Teacher: ...
I: Is the marble big?
Teacher: Yeah.
I: Oh, easy. Just use your hands take it out. HAHHAAAH!
Teacher: (I'm speechless)

Hahhaas, 'gik sei' teacher. LOL!
Blah blah blah. 其实，心很痛，是想隐藏，你说出问题说在的时候，我会有自杀的想法？
其实海鸟跟鱼相恋，只是一场意外吗？
