An elderly couple, had just learned how to send text messages on their mobile phones.

The wife was a romantic type and the husband was more of a no-nonsense guy.

One afternoon the wife went out to meet a friend for coffee.

She decided to send her husband a romantic text message and she wrote:
"If you are sleeping, send me your dreams. If you are laughing, send me your smile. If you are eating, send me a bite. If you are drinking, send me a sip. If you are crying, send me your tears. I love you."

The husband texted back to her: "I'm on the toilet. Please advise."
