To deal with somebody as he deal with you

Still remember I helped Khai Ming did his project last week ?
Erm, is a Moral Project.
Actually I just helped him do the title page only, like Isi Kandungan, Perhargaan and blah blah blah.
All were about 10 pages.
And what I want to say is, today teacher ask me to do Moral Project.
My Moral Project is about 30 pages.
I take this project's information to Khai Ming at first-hand.
Guess what ?
Surely ask him help me to do whole of the project without missing a single word.
This is what we called to deal with somebody as he deal with you.
Don't even moan and groan when you really helped someone that you not really know about him/her.
You might be need him/her help someday.
This post has show you guys an example. Lolz.
