Onyx actually found himself laughing a little. He wasn't trying to make fun of her. For one thing, he found it very odd being called a sir. He was used to calling others sir, or ma'am. He also had laughed because of what she said about FUBAR.
"That's close enough, and you don't need to call me sir. My name is Michael Winston, but you can call me Onyx," he said as he held his hand out.
Oddly enough he found himself a little less nervous than before. It seemed that she was just as nervous as he was, if not more. That actually calmed him down a little.
