Friday Funny

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."
