What does "she does go on a bit..." mean in the context? As often as not, we then immediately start grumbling about the very people from whom, a moment earlier, we could apparently hardly bear to tear ourselves. ‘God, I thought they were never going to go!’ ‘The Joneses are very nice and all that, but she does go on a bit . . .’ Even when we have thoroughly enjoyed the gathering, our appreciative comments following the long goodbye will be mixed with moans about how late it is, how tired we are, how much in need of a cup of tea/strong drink – and how nice it is to have the place to ourselves again (or to be going home to our own bed).
