Last night, my co-worker asked me to send her a copy of a document, but I was out of town then, and the document was at home. Hence, I promised that I would do that once I got home the next day. I got home early this evening and rummaged through chests and boxes for the document. I still hadn’t found it by 8 p.m., and I thought of giving up, but I found it even harder to tell my co-worker that I couldn’t find the document. She has been a respectable colleague, and I didn’t want to let her down. So I kept searching for it. Finally, I found it in a box late at night. I was tired, but it was worth it.
