I've actually been thinking about this perhaps too much lately as it is my favorite genre of Sci-Fi, and I want to write time travel stories. First, I hope that a good story can be written about people more or less hanging out in the past because I have a story idea along those lines.
Second, about your thoughts, I have thought similar, and as far as I know nobody has done that yet but someone probably has. There are so many random Sci-Fi novels and short stories out there that I"m sure someone has already played it out. But yeah, if you figure that if something happened, than it has
always happened. If someone going back in time will
always have happened, you can't really go back in time and screw something up because it will have always been that way. It doesn't make much sense if you superimpose that on our world as it is, but there are ways of making it work.
Regardless, continue to be my friend to see this idea as well as a number of others come to fruition as stories. Also, for anyone who doesn't know, the Royal Springs Entertainment Company is in its pre-pre-pre production stages on our movie, and it involves a sort of time travel that kicks much ass.
Also, Josh, I had a dream last night containing you and Andy. I was kicking it at my house in the Beach, and you and Andy were coming over to have a sleep over. You came over and wanted to do cocaine. At first we were hesitant, but then we were really excited for it. But, before you brought out the coke, you had to go home because it was past your curfew. We argued for a bit, but you didn't want to upset your parents, so you left. Andy and I were bummed for a moment, but then he remembered that he had a suitcase full of weed, and so we proceeded to get really really stoned and we prank called you and you thought it was awesome. End of story, and back to work for me!
