I used to think grown-ups had this rule that when someone didn't hear what you said, you had to say it in another way. I remember this happening when I was watching tv with my mom.
The woman on tv said: "I think we should break up" the man would say: "What?!"
and the woman would reply: "It's just not working out".
I found it strange that the woman just didn't repeat what she said since the man didn't hear her. Instead she said something else and I never understood why....
