如何令父母比零用錢給我呢?

1.答應父母在下一次的考試取得10名內。
2.請求父母每次幫他們做完家務後給你零用錢。
3.向父母反映為何你需要零用錢。
4.定一個合理金額的零用錢, 例如每星期$50
5.應承父母不會亂花錢, 取得他們對你的信任。
6.如果你的同學也有零用錢, 便說給父母知道, 好讓他們知道給零用錢是很普通的事。

partical ideas and reasonable.
In addition, I suggest you can list your expenses and discuss with your parents on this issue.

唔好咁naught,多d做家務,多d溫書...

比條件，eg：同媽媽講：我明天默書，如果拿了90分，可唔可以卑５元我

You can say : Mum,I do not have money. Can you give me some money ?
I want twenty dollars.
