PJ, it's because it's written down. There is no sense of irony, jest, calmness, interest, tone etc. You read it the way you read it and it is there in front of you, mocking you, impossible to delete, hard to ignore. I think I know what thread has got to you this time and I suspect you are taking what was said as different to what was meant ie I think a poster was pointing out an interesting way of interpreting your syntax, you assumed she was putting words in your mouth. The thing about MN is that usually it isn't personal and you don't have any of the physical markers to actually understand the way somebody phrases something. I once said that over-50s shouldn't have sex and was lynched and called 'young and silly'. Now, to me it's obvious that I'm joking but without my guffawing and saucy winking, they all misinterpreted it.
And did I say Freudian dream? I meant nightmare.
