I once had someone share something rather personal, followed up with a comment that they suspected I’ve had similar experiences.
The reason? The language and phrases I use when referencing parents. Nothing negative per se, but the way in which I refer to them (example: my mother) and others. I was giving away more than I realized.
Which wasn’t so much of a concern in this context, but I’m more away of it now around people I don’t know especially.
(This comment actually puts me a little outside of my normal personal opsec, but I’m going to let it stand here)
