Unexpected bits of niceness. I had to go in to get a report from my college dean for a transfer application, and I was in a bit of a rush. I didn't notice that I needed to bring a stamped envelope, and I was sort of blushing over how unprepared I seemed.
The woman who filled it out was quite nice though, and said that it was very common to forget the envelope. She filled out the paper, put it in her own envelope, and sent it out for me. It sounds cheesy, but it really made me happy.
