... take a few minutes to send an e-mail to someone who has been helpful to you.
I'm thinking about that because I assigned my feminist epistemology paper to my intro class (yea, it's kind of above their heads, but many of them are sharp and will get it). I got a lot of help on that paper from a person from whom I took no classes. She didn't have to help me at all, but she did and I'm grateful.
So, I decided to drop her a quick note to let her know that I was thankful and to let her know what was going on in my life.
So -- go, do it now...
