I recently got a really nice card from one of my dearest professors whom I haven't spoken to in a while, and I want to write back to him. I would think a card in return would be the proper thing to send. However, I don't have all that much love for my penmanship - it's not the worst by any means, but it's not all that good, either. The other alternative, typing out a letter, printing it on normal paper and stuffing it in an envelope, seems too impersonal. Perhaps I should just write a card out long hand - he's graded my blue book essays so he's seen my penmanship. I suppose I could just call or email instead. What would you do?
