A young blonde secretary was describing her blind date to a friend.
"After dinner," she said, "he wanted to come back to my apartment, but I refused.
I told him my mother would worry if I did anything like that."
"That was smart," her friend said, approvingly. "Then what happened?"
"He kept insisting, and I kept refusing," the secretary said.
"You didn't weaken your resolve, did you?" asked the friend.
"Not one bit. In the end, we went to his apartment. I figured, let his mother worry."
