Peter had arrived at Katherine's house early because he was so eager to take her out again. Of course, when he arrived there, Katherine was not home. Peter was forced to sit on the steps leading to her house like a complete tool. And that's what several people called him as they walked by. One even added 'haha locked yourself out of your house, Tool?' before continuing on his way. Peter thought people were mean.
