Just now, one of my coworkers called me up and told me that her mother had bought sweet (white) cherries and she'd brought some with her to work. She remembered that I particularly like sweet cherries, so she was saving me some. When I went to her desk, she said she'd saved me some of the best ones. :)
I thought this was particularly nice--not just that she was sharing, but that she remembered what I like. It's this sort of little thing that makes a difference in someone's day.
