When you’re in a call and you want to talk to someone or a couple people, but you’re in a group with someone you don’t particularly care for. So you have to sit there and listen to them overtalk and maybe you don’t even like their voice. But you can’t mute them or be rude so you have to waste time until they finally leave.
When people just keep saying “and then,” when explaining something in a presentation. It’s the kind of run on sentence that can go on forever.
