A woman goes to her psychiatrist because she's having severe problems with her sex life. The psychiatrist spends an hour asking her questions, but he doesn't seem to be getting any closer to the root cause of her problem.

Finally, with just a few minutes left in their session, the psychiatrist says, "Do you ever watch your husband's face while you're making love?"

"Yes," she says, "I opened my eyes and watched his face once." "Well, how did he look to you?" "He looked angry. Very, very angry." At this point the psychiatrist feels like he's finally getting somewhere, so he says, "That's very interesting. We must look into this further. You say you've only seen your husband's face once during sex and that seems somewhat unusual. How did it happen that you saw his face that one time?"

The woman says, "He was looking through the window at us."

Spoiler .. peeping Tom. No wonder her sex life was spoilt.
