The reason for my title is that I'm getting increasingly frustrated with posters who clearly have not read all the preceding posts by the original author of the thread. There is a recent one about Mothering Sunday that is a classic example - the poor (and extremely patient!) OP is having to repeat the same points over and over and over and over..... again, simply because contributors have not read all her posts.
Now, I entirely appreciate that it's not always possible to read every post on a thread - of course not! - but surely it's possible (and, I would say, essential) to read every post by the initiator of the subject before making a response.
So, AIBU? Or is it okay to just launch in without reference to the opening poster's actual situation?
