My Sister and I ...

My sister and I were at the mall and passed by a store that sold a variety of nuts. As we were looking at the display case, the boy behind the counter asked if we needed any help. I replied, "No, I'm just looking at your nuts." My sister started to laugh hysterically, the boy grinned, and I turned beet-red and walked away. To this day, my sister has not let me forget.
