Like this ?[@Spriggs27][@6slyboy6] :

Rachild turn back and he look at the stranger.
He turn back and he start to search something with a suspicious look.
He found a rock and he send this on the windows
After that he run away from here with a laugh 

That could be better for me because i can't use the part correctly --
And that could be less boring

Like try to use commas.

Rachild turned back to look at the stranger but decided to not be bother by him for now, he turned back to continue searching with a suspicious look on his face. He had found a rock between the hit of waste at the side of the street and sended it flying through the window, quickly he made a run for it to not get caught by the house owner.

If you use commas, but and and you can make the lines longer so that they will flow into each other.

I dunno im not english myself either though.
