of course dah that is what we do with everything

Not reading in..... But rather not able to read for comprehension.

I assume you are correct in your assumptions.

You touch upon a complex area of human communication.

As @diaco suggests, face-to-face communication is much richer than just words written on an (electronic) page, and so that form of communication can disambiguate a lot of possible ambiguity.

As @p-nullifidian suggests, it takes time and effort to read other people's words closely and to ponder the writer's real intentions. Again as he suggests many people don't bother to do that.

For myself, I am aware that any given word or phrase can mean different things in different parts of the English-speaking world.

As @lerlo suggests, people can change the meaning of words in their own minds to suit themselves.

Looking at your own bio, I would suggest that it might be a mistake to think that even 10% of the population has your own analytical habit of mind.

I hope this helps.

You're correct. It's amazing how people here change whatever your post is to what they want the post to be. Just get used to it and carry on

Sometimes what you write reminds the reader of something they have seen or experienced in their own life that perhaps you have not.
Being quick to toss out any reply that seems like an "assumption" to you is to actually negate your post....why ask a question if you are so sure you already know all the answers?

Most of us, maybe all of us, seem hardwired to immediately react to what we read. It is only upon a rereading, and a reflection on the original comment (and more importantly our response), that we can better gauge our emotional—intellectual balance when posting to the site.

Hmm, always there's chances of misunderstanding, especially in social media, in real life we use body language, voice dynamics, and all to make a clear and better connection but here we just have words. so take it easy, it's normal

I think that’s just the way people are.
Always.
