So I have this Head-canon that Sadie is like half a foot (or maybe even more) shorter than Anubis (okay, we're comparing a 13 year old girl to a 5000 year old boy-god here). Not to mention Walt, which Richard Russel Riordan has pointed out that is very big and muscular. So when Sadie and Walt/Anubis are watching a movie, they spoon, but whenever Sadie is the big spoon, she just fits on like a back pack. Because of this, Walt/Anubis are the victims to giving many piggy back rides, and if they refuse, they recieve endless teasing until they oblige to Queen Sadie's demands.
