Maybe they should consider purchasing Rosetta Stone.

Continuing on with the line of thought that brought me to believe that maybe, just maybe, R2-D2 was saying a lot more than everyone thought he was, so too have I come to believe this about the Tusken Raider that attacked Luke at the beginning of Star Wars Episode IV: A New Hope.  You see, it all started many, many years ago, when Anakin massacred that Tusken Raider encampment.  Now, I have to believe that he didn't get everyone.  That maybe someone escaped, or someone was coming back to the camp from the hunt and that they saw what happened.  Now, this surely would have really messed up whoever the witness was, and would have surely created the need for revenge, but unfortunately by the time the posse was put together, the perpetrator was long gone, leaving the seeds of revenge and anger to grow over the years, the story of the lost tribe spreading across the planet until that last remaining Tusken Raider learned that the son of the slayer just happened to be out in the middle of nowhere with only a couple of robots to serve as his protectors.  Now was the time for revenge, and so, the lone survivor set out across the Dune Sea and finally came upon the young man he had been seeking, and it is here, after knocking him to the ground that he said something to the tune of , "Hello.  My name is (insert Tusken Raider name here).  You killed my father.  Prepare to die," a la Inigo Montoya from The Princess Bride.  Now, I'm not saying that that's what he said, but well, Lucas didn't bother to give the guy any subtitles, so you can't very well say that it wasn't.

(Besides, I'm sure that more than one citizen of Tatooine wanted to do Luke in.  Let's face it, the guy, or his father, managed to mess up quite a few lives, not the least of all those of Owen and Beru.  I still feel sorry for those two.  I mean, Owen just wanted to farm moisture and Beru just wanted to make drinks of varying colors.  They meet Anakin once, end up having to raise his kid, and what do they get in return?  They get to be a couple of burnt skeletons outside of a sand igloo.  Now that's gratitude.)
