Excuse me, can you repeat that? 

I'm sorry. I didn't understand what you said.

All I hear is mumbling. 

Sounds as though the world is a Charlie Brown cartoon.

Seems as if all I say is 

"I'm sorry, what did you say?" and

"Can you repeat that?"

Oh.  My name was called. 

Now she's angry.

Sorry for imperfect hearing.

Sorry for having you repeat yourself.

Life is complicated enough. 

I feel like I am bothering every person I talk to.
