You know the drill - If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one.
3. Open Threads should start on Monday, and end on Sunday.
4. Open Threads should be posted in Discussion, and not Main.

I speak about repressing certain things for longer periods of time. Not something where you repress your trauma one day and don't do it the next. You can do the change in a single day. Even in a minute but that's not what happens most of the time.
