They figured it out from the very beginning. And they decided to live there at least during the summer. Woman started out to cook in oven because she had an innate ability to good cooking. Man was always moving because he had the roller blades. One day along the way to the house from his seal hunting he encountered with suspicious fiction. He saw very astonishing bush and he aspired to leap above it. He was obsessed with flavors of that bush. And he fell down and hit his shin splints by the ground. It was a realm where he shouldn`t leap. And his decision was spontaneously. When he came back to his wife he was too scared. She was looking for affordable fare of their flight. And when she saw her husband she kept trying to bring up him. They make the vows to each other not to hang out through unknown locations. And they kept their vows in effect till the end of a journey.
