Flying away is when you leave the place you grew up, by yourself, and you also leave your family (but not forever), usually to somewhere that is different than where you grew up. You don't have any intentions of returning, and you are leaving behind everyone for a better life.
an example of flying away is when you grow up in the midwest and move to the southwest coast in California because you hated cold weather, you are only coming back to see your family.
A Shackteau is a humble, weather-beaten, structurally questionable shelter located in a spectacular or highly coveted place—Wales, Jackson Hole, Sun Valley, Crested Butte, coastal Maine, the Alps—where the building itself may be worth almost nothing, but the dirt, view, access, and mythology make it absurdly valuable.
