They say a picture is worth a thousand words — and in this case, a book title.

In celebration of World Book Day on Thursday, March 2, UK-based elevator company Stannah put out a tweet challenging followers to identify 10 classic kid’s books by using emojis as clues.

“In celebration of #WorldBookDay, we’ve created a brainteasing #book emoji quiz,” tweeted the stairlift and home lift company. “Our #SilverCensus study saw us ask more than 1,000 over-60s which stories they feel all children should read… and these sequences represent the top 10 answers”

Stannah’s tweet comes amid uproar from Gen Z about the nature of emojis and their apparent misuses.

One Reddit user caused an online firestorm after demanding that the thumbs-up emoji and nine other emojis be canceled for being too passive-aggressive to use in an office setting.

“For younger people, the thumbs-up emoji is used to be really passive-aggressive,” wrote the user.

“It’s super rude if someone just sends you a thumbs up,” they added. “So I also had a weird time adjusting because my workplace is the same.”
