At a dinner party, several of the guests were arguing whether men or women 
were more trustworthy. "No woman," said one man, scornfully, "can keep a 
secret." 

"I don't know about that," huffily answered a woman guest. "I have kept my 
age a secret since I was twenty-one." 

"You'll let it out some day," the man insisted. 

"I hardly think so!" responded the lady. "When a woman has kept a secret 
for twenty-seven years, she can keep it forever."
