tinyE: okay, DID YOU WATCH EPISODE 1-3!?
First off: DIE for using the new Star Wars films as an explanation for ANYTHING related to the old ones.
tinyE: They were in hiding!
So what? Famous people also often try to get away from it all when they get older, doesn't change the fact that it's retirement.
tinyE: He was told to lay low on Tatooine until the Luke came of age and could then be trained up and sent off to confront his father, kill the Emperor, and save the galaxy.
What made him get up was a distress call he wasn't expecting, it was *his* mission, he may not have even taken Luke with him if it hadn't been for those stormtroopers who had burned up his home and killed his only family.
tinyE: Yoda was in hiding too. Why the hell else would anyone live in a swamp?
Because of the weed, dude. Why else was Yoda so messed up? Confused, talking non-sense, stealing candy bars... and why did Luke get those visions? It's swamp weed and shrooms, dude! It's paradise for cool fellas like Yoda. Talking to trees, dancing in the mud, fighting your dad who happens to have your face... it's awesome.
