One way to know if you are friends with someone is to check if you are comfortable with ignoring them.

People who spend crazy money on the coolest newest phone (ie. the foldable one) absolutely love hearing you ask about it. They love it a bit too much, maybe..

Avoid starting texts with “Anyways, …”, which usually sounds stilted and weak. It’s a new text as it is, you no longer need that transition.

When someone wrongs you slightly and then realizes and feels bad for doing it, you can “punish” them further by acting all submissive and making them feel worse.

Saying something on a chat, and then immediately saying its semi-obvious counterpoint, shuts down conversation.
