- knowing when your friend is out of the house, because their phone capitalises their messages
- noticing they’re down because that was the wrong emoticon
- lol vs lmao vs hahaha vs ahaha
- subtly wrapping your schedule around the edges of timezones on the other side of the world
- conversations that play out over a week because you’re both perpetually idle but you want to know how they’re doing
- not being able to wake up for an alarm, but leaping halfway across the house for the message alert you’ve been waiting for
- talking to the same person about different topics in three conversations simultaneously
- knowing when your friends have been spending time together because they start to type alike
- watching them start and stop typing over and over and not interrupting, because this must be important
