Visual and audio confusion.  

lol!Yep! Just the other day I saw a real petite woman who sounded like a man! Or you see this big manly looking rough guy and he had a real high voice! It can be real confusing to the head!

Ah yeah I've experienced this a few times. The one that comes to mind right now is the first time I talked to my wife. Back then she wasn't my wife. I had just started talking to her. But when I heard her voice it just really confused me. My wife is a filipina girl. Its an asian country for those of you who don't know (Philippines). She looks a little bit more asian than most phils. So I was expecting she might have an asian accent. Either very little english, or very good english with an accent. I was not expecting a british accent. She had an english accent like she was born and raised in the frikin queens bedroom. I would just stare at her, and wonder where that voice was coming from. Now she has my accent though. I talk to her alot. I was kinda hoping I would pick up her accent though. No one is impressed by an american accent.
