I know someone that actually happened to. He went home for Thanksgiving Break in college, and his parents had moved without telling him. He had to go back and spend Thanksgiving in the empty dorm. His patents later claimed they just forgot.
When I came home for my first college break, I saw a For Sale sign in the front yard.
Mother told me the move was short-notice and with four kids in the home (two in High School, two in Middle School), she was distracted and forgot to tell me.
Funny, as I could see that happening (dad already moved to the new job and my mother was selling the home, packing and getting my sisters ready for the move—sisters. . . drama galore.
