Teenage daughters
 

Three women are discussing their teenage daughters.
The first declares: "I was so shocked last week. I was tidying my daughter's room and I found a packet of cigarettes under her pillow. I didn't even know that she smoked!"
"It gets worse than that," says the second mother. "I was tidying my daughter's room last week and I found a bottle of vodka under her bed. I didn't even know that she drank!"
"Oh, it gets even worse than that," says the third mother. "I was tidying my daughter's room last week and you'll never guess what I found in her bedside cabinet: a packet of condoms!"
I didn't even know that she had a penis!
