Sure certain words or things can trigger painful memories and thought chains but you have the eyes to see where this is going, the brakes to apply so you don’t crash.
Resolving every thought problem is a fool’s errand.
While you are solving one 10 more can appear.
Which is why it’s important to dismiss and move on.
Even that requires a level of detachment that can only come with practice.
Also, as we already know it’s not necessary to avoid pain, or to dwell on it/engage it.
