Sometimes I'll start to say something and then realize that it wasn't very interesting and shut up. This frequently annoys the people around me who will say things like "What? What were you going to say?" I'll say the thing that I was going to say and they will generally comment on the inanity of it. This seems rather unfair - if I didn't think it was inane I would have said it in the first place. You can have the filtered or unfiltered version of my comments but don't expect the unfiltered comments to be up to the standards of quality of the filtered ones.
