That has been stinking

About two weeks ago, a sound of something stepped on a plastic bag on the floor woke me up at 5 am. When I woke up, I heard the sound of something went up the stairs from the third floor to the the rooftop. I guessed it was a mouse because I heard the sound of a mouse went down the stairs from the third floor to the second floor. I shone my flashlight the door of the rooftop from the third floor. There was a bigger one there than I thought. It was weasel. It tried to go down the stairs, but it couldn't do because I banged on the stair. I didn't know why I did. Since my father had woke up, the sound bring him to my room. I opened the door of the veranda on the third floor and we let it go. When a weasel is attacked, it gave out a bed smell. I didn't know that! It went away, but that stinks a little.
