Your friend’s annoying phase is probably temporary. You’d want the same grace for yours.

People go through stretches of being hard work, and the stretch is usually about something you cannot see. A friend who is currently irritating may be under pressure, or trying on a version of themselves, and most of those phases end on their own if nobody makes a permanent decision in the middle of one.

Give somebody a few more weeks before you draw a conclusion. Keep the friendship open at a slightly lower temperature if you need to, and ask once how they are. Remember what you would hope for during a difficult stretch of your own.
