【英文原文】

Come in an envelope——坐信封过来

Torrential rainstorms were knocking down power lines all over town. That meant, as a customer service rep for the electric company, I was dispatching repairmen right and left. When one lineman called a customer to get her exact address, he was told, "I'm at Post Office Box 99."

　　The weary lineman replied, "Ma'am, I'll be coming to you in a truck, not an envelope."
