it's my life

A man comes home with his daughter, whom he has just taken to work. The little girl asks, "I saw you in your office with your secretary. Why do you call her a doll."
Feeling his wife's gaze upon him, the man explains, "Well, honey, my secretary is a very hardworking girl. She types like you wouldn't believe, she knows the computer system, and is very efficient."
"Oh. I thought it was because she closed her eyes when you lay her down on the couch." the daughter said.
