Did he juz say that or has he been doing that??
You know sometimes when we get fed up of family and a monotonous life, we ourselves wud say 'I wanna get away to an alien land for sometime'...atleast I say this whenever I get stressed due to people(relations/friends)...if this was juz a statement that he said, I wud hv probably thought that he juz was stressed out but if he was doing this, then a definite background check is recommended...
juz my 2 cents
