I liked the emotion and mood of this; it was conveyed and maintained well throughout. My only concrit doesn't even have to do with the character (just technicalities). Some of the sentences were a little long and awkward--the second and third paragraphs, mostly--and I think you could have captured the same mood if the sentences there were broken up and polished a little bit. But besides, that, I liked the image of Donna packing up her desk and the touches of bittersweetness. I think it captured her frame of mind at the time really well. =)
