Daaaaaaamn.
I am really sad but at the same time, his family was there so he must have known. This was something he was looking forward to even if it wasn't by his own hand.
So RIP Sir Terry, you've changed me and how I looked at the world with your funny characters and your brilliant words and engaging setting. You've given me a fictional role models, a safe haven in Ankh-Morpork, you got me excited about reading again, you pulled me out of depression, you reminded me that with all the bad in the world there is comedy too, and it takes a strong person to laugh at themselves. You changed my life for the better, sir. I hope you get a good bowl of curry and a kitten on your walk.
