I think we have a new family handshake

Tonight I didn't want to cook, so we went out to dinner at the Mexican restaurant around the corner. At some point during the meal, Adriana and Brian made some sort of deal (I think about staying in her chair). "Shake hands?" Brian said, extending his.

She looked at him for a moment and then studied her hands, obviously befuddled. Finally, she shook both hands in front of her, as she does after she washes them, to shake off the water. Then she went back to her rice and beans and fish, while Brian and I cracked up. 

"Should I teach her how to shake hands?" he asked.

"Oh, please don't. This way is just too cute."
