Decorum isn’t about stiff rules; it’s more like subtle restraint. Emojis like 🤝 and 🎩 signal respect or formality without saying it outright. Use them in a post-interview text to show you’re polished or in a group chat when the mood calls for a bit of class. They work well when you want to keep things courteous but not cold, like responding to a delicate topic or signaling you’re taking the high road.
