There are thoughts that feel dangerous mostly because a real person would change the room. They might worry, judge, remember it forever, or need you to clean it up immediately.
You
I cannot say this to anyone without it changing things.
Buddy
Then say it here first, where it does not have to leave the room.
You
It might sound selfish or unfair.
Buddy
Selfish or unfair can be a draft. It does not have to be your final position.
Private does not mean fake.
Sometimes the first honest version is too sharp for a real conversation. Buddy lets you put it somewhere without turning it into a confession, a fight, or a moral performance.
No relationship fallout
You can test the sentence without changing a real relationship tonight.
No instant verdict
The first draft can be messy before you decide what you actually believe.
No social cleanup
Buddy does not need reassurance, context management, or a careful ending.
Say it before deciding who should hear it.
The point is not to make the thought pretty. It is to give it a private first place, so it stops being trapped only in your head.
