twin in a book

I am going to show you my new book that i bought last week. Actually, im a bit embarassing because this book supposedly for the teenager level. But, never mind.

The main reason i bought it is because i found it easy to understand when i go through to certain pages. The author use a simple english and some more, the book has been compiled to one. Originally it was 3. 3 in 1 like instant vico drink. So, I already did a little saving there. Hehe.

I was so happy to find one. Hope i can brush up my english skill which has been rotten a lot. Rotten?  APAKAH..

I always did this kind of expression when someone trying to make silly jokes which he thought it was funny but its not. 

You jokes quite lame, lol...
