The funny thing about English

I just thought of a weird question in this year,2007,'s SA1 english exam paper.The question is in the synthesis part and it goes like this.-Bala is very careless.He lost his wallet on the way to school.-And I wrote-Due to Bala's carelessness,he lost his wallet on the way to school.-And then I got it wrong.My form teacher,Mrs Lee-Goh says that if it is written in this way,it is saying that due to Bala's carelessness,it causes another person losing that person's wallet.And because of that it should be-Due to his carelessness,Bala lost his wallet on the way to school.-But then now it sounds to me that due to other person's carelessness,Bala lost his wallet.Mrs Lee-goh says that it is english language rule so,no choice.Then,Sean,who was sitting behind me at that time in class says that it should be-Due to Bala's carelessness,Bala lost his wallet on the way to school.-to the people sitting around me and also including me.But then,I said it should be-Due to Bala's carelessness,Bala lost Bala's wallet on Bala's way to Bala's school.-HAHAHAHAHAHA.Thinking that it is very funny.But then also someone sitting around me,who I forgotten who is it,says that it may means that due to this Bala's carelessness,that Bala lost another Bala's wallet on another another Bala's way to another another another Bala's school.HAHAHAHAHAHA.So English can be very funny if you play around with it but somehow I am just not good in English because I like to read chinese comics!(Although it doesn't seems to me that my English is bad is caused by me reading chinese comics).
