I hardly ever read things into other people's remarks. Maybe I'm stupid or insensitive or unimaginative, but I do tend to take what others are saying at face value. I don't assume there's some subtle meaning I have to tease out.
I remember a woman I knew telling me she always read too much into what others were saying. This had led to a few heated arguments with her boyfriend when he insisted that what she was imagining was nonsense.
Journalists are front-runners in interpreting people's remarks in a hundred different ways. Could that politician's chance remark mean they're considering resigning? Or they're getting dementia? Or they're angling for promotion? Or they're panicking over some imminent scandal? Of course most of it turns out to be claptrap.
Actually I'm fibbing slightly when I say I don't read anything into people's remarks. I like to be liked and I do try to figure out from what someone's saying whether they like me or not. Did I detect a certain frostiness there? Did I detect a note of warmth? Did they agree with what I just said? Did they look disapproving? I can't quite go along with the "just be yourself and don't worry about the reaction" brigade.
Mostly I confine my speculation to novels and the fate of fictional characters therein. Whether I guess right or guess wrong, it's of no consequence.
