Ruth's correction is good; here's a variation.

Reading

It's sort of strange that I don't like the pages of all my books to be clean and tidy,
I like to write down something on in them...
So that when I pick up the book again after years later, I might understand what's my feelings when I first read it.
It's like conquered it by destroying it XD
They're mine and I won't sell them to a second-hand book shop!
Still, I like to buy used books, they're cheaper, so that I could I can buy more...
I love buying books, even though I have lots of books waiting for me to read them =)
When it comes to used books, I prefer them to be tidy and looked to look completely new.
I want to give them another life by writing something down on in them =)
