Hi jennyjoan,
I have not read the thread in question, but I, and indeed most regular posters on here, have fallen foul of misunderstandings between intent and receipt, which can cause issues.
It is the curse of written communication, which has the time delay of being read and (mis!)understood before a reply comes back, and this can and does cause issues.
The best way around it is to accept that maybe what you said was not clearly picked up by one or more readers, and that is no-one's fault, it is simply a bugbear we have to work around.
Hope this helps.
