The messages still glow on my screen: "meet you there!" and "can't wait!" followed by strings of emojis. 2:47 PM, July 15th, 2167. Someone's excitement, it's there. The diagram maps these moments - each timestamp a doorway to when messages were instant and laughter was easy. We didn't know we were creating archives of happiness, cataloging the last normal days with each casual "talk later!"

Looking at old group chats is like watching a timeline split. There's the path we thought we were on, caught in those bright conversations about some future plans, and the path that actually unfolded. Every "miss you Sahbi!" and "let's do this again next week!" becomes a marker, measuring the space between what we hoped and what ends up happening. The system doesn't show when things changed - it shows how we never noticed they were changing, until one day we found ourselves scrolling back, searching timestamps for clues about when everything was still ahead of us.
