@Stahesh Perhaps he was just "in his own head" too much and did not know how to solve problems or was too intimidated to seek out help?
Perhaps, he was just a narcissist, like you observed.
Today I'm at a different beach, further Northwest, and it's funny how it's 98% German tourists. Whereas in Malia it was perfectly British territory, along with pubs and whatever your average Brit expects. Funny how even on vacation, and even if they're related (like Germans and Brits are) people tend to segregate automatically.
