a fools message
You leave a message that makes no sense. You don't say why you called or who you are. You just talk about random stuff and then you realize the other person is just a machine and you're too proud to stop.
I left a message saying I was mad about my job. I didn't say who I was or why I was mad. I just talked about my coffee and how it was too hot.
I left a message saying I wanted to go to the park. I didn't say who I was or why I wanted to go to the park. I just talked about my dog and how it was too loud.
I left a message saying I was sad about my life. I didn't say who I was or why I was sad. I just talked about my phone and how it was too slow.
