If i saw the Jackson kids walking in my neighborhood i would go up and say Hi to them and just talk about alot of things like what is their Favorit cartoon and ask them other Zufällig things like their Favorit color of movie. But i would be so excited if their were walking down my neighborhood. :)
i, personally, would go up to them and talk with them, invite them into the house, ask them how things are going and a couple things about how their life has been not having their father around, but knowing that he watches over them all the time. maybe (if i was a Medium) give them a Lesen and have them be able to sense Michael in the room with us and such. I'd just treat them like normal kids, play with them, be Friends with them and such. I wouldn't wanna treat them like Michael's kids forever. They do miss their dad, but they get a chance to be normal, so it's a good thing.
