I don't know if anyone else has ever done this - or will admit to doing so - but I did something today that I've never done before.
I've been reading stories that affected me so much that I've gotten emotional about them - especially many war stories. But I've never been WRITING a scene that made me emotional. Seriously had to take a time out, blow my nose and wipe my eyes. Twice.
Yes, it was the death scene of one of the sub-characters, but ... damn, so much for being a tough old fart. :)
