It annoys me when i try to end a conversation with somebody and they are still talking

I dont have the patience sometimes. A friend messeged

Him: what you doing?
Me: At work about to find something to watch
Him: i'm watching knives out with the family
Me: Cool! okay enjoy the movie with your family holler at me later
Him: what are you going to find to watch?

🙄 Bruh i already ended the conversation if i say "holler at me later that means i'm OUT" and he's still messeging me lol
