When that one friend is still the most important to you, but all you have left is memories
You still remember:
The way they like their chai, always extra sugar at the bottom (chai in the cheeni, not cheeni in the chai).
The way the two of you listened to songs together, songs you would never admit listening to (and liking) to anyone else.
The way they needed to explain something they were extremely passionate about and you did not have to pretend to care, everything about them was as important to you as it was to them.
