One day, Justin saw a little spider and it scared him. He decided to grab his 20 pound sledge hammer to kill the spider since nothing else would do the job. By the time he got out his hammer, which was clearly too heavy for him to wield, he could no longer see the spider. “Why am I holding this hammer?” Justin asked. He decided to put the hammer back with the comfort of knowing that it would be there waiting for the next little spider.
