The book was a surprise! It was when I was in a darker place and you said it helped you through rough times. I hope you grade them harshly when they use the wrong form, however.
The book must have fallen into a dark place itself. As for the students, I tell them that deadlines are guidelines. It's probably not a great idea pedagogically. Now the postcard and letter are definitely on their way to you... and apparently I owe you a book. I hope you are in a lighter place now.
I made a post on reddit the other day in the SRS private subreddit where I touched on it lightly. Hubski did a lot to help me out, because I was obsessive at the time over the idea of 'creating a better world' and living with technology as we do so deeply ingrained in every part of our lives, that people should be better and we should be progressing towards something better overall, especially with connecting with people and having a better understanding. I was depressed and didn't see much good happening and any way and was disappointed in society as a whole for failing to do that when we have the ability so there. And then Hubski comes along and does do a lot of what I would hope to see in an internet community. We have the personal connections and the driving force of understanding that it did provide a lot of support while things in my life got better overall for me. So yes, most certainly a lighter place. Much more proverbial guidelines and less strict deadlines.
