context: Will wanted to go bowling with his friend Allen, but he didn't have enough money to cover the cost for both him and Allen so he just went alone. Will brought his own ball and when he stepping in the door he could smell that fresh bowling smell. so Will went up to the counter and asked the woman operating the shoe station for a size ten pair of shoes. He laced up his shoes and was ready to go. he saw an open court and he took it. he pressed the new game button and off he went. he saw that the pins were set up in a very specific way but he was ready for that challenge. he rolled the ball so far onto the lane that it knocked out all of the bowling pins and he received a strike! everyone was so amazed. Will did amazing. he kept bowling until the night ended.  he got so tired that he eventually had to call it a night and go home. Will returned the bowling shoes and laced up his old regular ones again taking those shops off was like taking power away from him. Will got back in his car and drove back home.
