MANESHITAI : I wish I write like xxxx

Hi, This is Banana.

I am reading a book.
It is Hardboiled crime novel.
It is "GUN MONKEY" by Victor Gishker.

While I read it,
I found a lot of cool fraze.

For examples,

(1)When a hero say bye-bey to his girlfriend,
======================================
I kissed her. "I'll be in touch."
======================================

(2)When a man warned , he said,
====================================
"You're digging your own grave, you fool."
====================================

(3)「しゃべるから、殺さないでくれ」。でもなかなか
　　しゃべろうとしない男に
==========================================
"You said you'd explain," I reminded him.
==========================================

I will use these cool frazes !
I want.

Do you have such cool fraze that you like to use ?

"I'll be in touch."
