I swear to god - What you say to someone who won’t stop talking about somethi

What you say to someone who won’t stop talking about something you don’t care about and also won’t stop talking about it.

'I swear to god, I’ve heard about your dog’s dog’s dog.'

'I swear to god, I’ve been listening to your story for 10 minutes and I still don’t know why your dog is sad.'

'I swear to god, if you talk about your dog one more time I’ll start talking about my dog’s dog’s dog.'
