I think this going on a bit has to do with age, when you are younger you go on a bit about subjects not realising that you may be offending someone. As you get older you tend to go through a phase of not going on and then you start to close in on middle age and strt going on a bit again this time (maybe) not caring that you may be offending someone. ( I have known people who do that)

Anyway bert, you can go on as long as you like for me, having too little to say is worse than having too much to say.
