Where I work, there a just a couple of us that live in a particular area. Not far away, but north, and most people here live south.
One girl knew I lived not too far from her, and asked one day if I could give her a ride home. That ride home turned in to almost a month of picking her up and dropping her off every day. Don't get me wrong, it wasn't the distance to give her a ride. It was the fact that EVERY morning, when I arrived, at the same time, she was never ready. I mean, never ready to the point where there was mother than once that I called her to let her know I had been ringing the bell and knocking with no response.
How did I get out of this? Easy. My sister fell and broke her arm. I told coworker I had to help her get dressed in the morning and wouldn't be able to give her a ride any longer. She stopped coming in to work.
