Story of the Day 12/ 3/ 2012

I was at the store with friend of mine, who is Deaf.
I was interpreting what the cashier had said, when the cashier who, judging by his accent is a native Hoosier, asked, "So, you speak German?"

My friend's response was exactly what I was thinking; so I voiced, "German?"

"You know, with your hands."

My friend and I were very glad for the explanation, but also unsure what to do with it.
