I'm beginning to realize why I like the book reading emote so much: It's what I'd call a good "waiting room" emote. Prior to the Season of Moomin starting, the boogie, levitation, or headbang emote were among my most used emotes because I'd use them while waiting for something (Geyser, Grandma, etc.) The book reading emote fills this niche perfectly. It's as close as we can get to having your skykid scrolling on a phone.
I like this emote and this particular use case so much that I'm considering bringing a stool where ever I go so my skykid doesn't have to sit on the floor.
