A friendship is solid when you can say “that hurt my feelings” and it doesn’t end.

Durability is the thing being described here, not comfort. Most friendships never get tested because nobody risks the sentence, and so both people spend years guessing. Saying it out loud puts weight on the structure, and a strong one simply takes it. The ones that collapse were being held together by nobody ever mentioning anything.

Try the plain version next time instead of going quiet for a week. One sentence about the specific thing, no case built around it. Give them a minute to respond badly before deciding what it means, because people often recover within the same conversation.
