John was getting ready to move into a new house. He was excited but needed to do some work on the house before he could actually move in. He decided he wanted to replace the carpets in the living room of his new house so he stripped the old carpet of the living room with his buddies that were there to help him. He pulled up the carpet and got rid of it and made sure the floor was okay. It was fine to work with so he got the padding for the room out of his truck and brought it into the living room. He padded down the floor with his friends. He put it down across the entire room and proceeded to get the carpet out of his truck now. He brought the carpet in with his friends and placed it down across the entire room. He was happy with how it looked with the finished result.
