When Maelle Kouman, 24, turned off auto-capitalisation on her phone as a teenager, she didn’t realise it would become a lifelong habit. “Lowercase feels like an ongoing conversational tone without a start or end,” she says. “It removes the serious tone certain texts can exude, even without trying.” Ruweyda Hilowle, 24, has also turned her back on capitals. “I text in lowercase because it feels more relaxed,” she says.
