I was gonna say something but I forgot =/

Well I was thinking about what Ben had said to Jack, "What do you have back at your home?" or something along that.

If you think about it, all the survivors have been on that island for a long time. For the first few days everyone was expecting to get rescued, but no one showed up. Everyone had to get used and adapt to the island, if no one was showing up, they have to start living there. I'm sure a lot of people would begin to forget about going home, the island was the new home, Jack switching back to L.A. was like him crashing on the island (this is all my opinion) he hasn't gotten used to being in a city, with his job back etc.

SOrry if that sounds weird I'm not very good at telling my opinion
