Happens on here all the time.
People read what they want...they see things thru their own perspective USUALLY without thinking about how the writer may have meant it...and often a reader's interpretation is completely different, and a reaction may not always be to the message but how it is delivered as you stated. I even get annoyed with texts...sometimes I am wrong in my interpretation, sometimes I am dead-on. I know I often react before thinking that perhaps the writer meant something else...I am working on that!
Oh and by the way, feeling pretty good...mostly good- always a bit of unease but definitely getting better. I think so anyway.
