A lady in her mid twenties climbs the bus, slightly out of breath and with bright pink cheeks.
All the seats are full. She looks at the gentleman sitting closest to her, and says: "Are you not going to give your seat to a pregnant woman?"
Blushing, the man stands up. "Sorry, I had not noticed..."
As she sits, he looks at her. There are really no signs of a protruding tummy... He asks: "How long have you been pregnant?"
"Fifteen minutes. My legs are still shaking..."
