Lines aren’t just visuals; they’re punctuation marks in emoji form. Use ➖📝 when signaling edits or notes, 📐➖ for geometry chats, and ➖📄 when referencing documents. Double 🏁🏁 or 🚉🚉 give a sense of races or journeys, adding context beyond simple text. Sometimes a neat ➖➖➖ breaks up your message for clarity or style. Great for project updates, classroom banter, or race-day hype.
