Some folk rabbit on, making almost impossible to get a word in edgeways. They're worse than the interrupters and the sentence-finishers. They also use to body language as another way to force you to remain there as the person they're talking to (or rather, talking at). One of my neighbours is like that, meaning that careful timing is required, to make sure my trips to the shops aren't delayed by half an hour, as they bang on about whatever their current issue happens to be. And if the topic of the day is local gossip, my neighbour will speak very quietly, so that they won't be overheard - even if it's obvious that nobody else is within earshot!
