It drives me mad!
some people post something that has happened to them.
people offer advice.
problem often changes midthread because situation is now different and they feel reassured blah blah
or they resurrect a thread from a while ago and the problem is different
some wally doesnt bother to read the thread because they cant be bothered!! and offers more advice about the original problem!
I have seen it happen on so many threads and one poor mumsnetter who had had a terrible time and lost a baby didnt come back because of the insensitivity of another mumsnetter who hadnt read it through.
Rant over.
