Drunkalogues.
I have had a good run of three meetings. Currently this particular night has one drunkalogue after another but three successive speakers have given really insightful and challenging chairs.
I have to say that I find drunkalogues tedious. However, the observable fact is that the people who tell them, either in a chair or in a share from the general meeting, seem to stay sober that way. It is not for me to criticise.
