Don't Tell my Mother

After years of hard work, Angie took her first vacation on a luxury cruise ship. While sitting in a deck chair, she recognized a former high school classmate, a long-lost friend from her old hometown.
She crossed the deck and shook hands with her friend and said: Hello, Angela. I haven't seen you in years. What are you doing these days? 

I'm practicing law, whispered Angela. But don't tell my mother. She still thinks I'm a prostitute.
