'Change the subject' immediately backfires in the funniest way

A chat where someone clearly doesn't want to talk about their mood. Friend asks why they seem down with crying emoticons. Blue bubble replies 'No reason lol lol — can we change the subject?' Friend goes 'Okay.' Then immediately says 'Oh, today I had lunch with my junior.' Blue bubble fires back: 'I said change the subject.' The irony? The friend changed the subject... straight into something that's obviously the reason for the bad mood. Brutal self-own.
