A man and a woman were having a quiet, romantic dinner in a fine
restaurant.. They were gazing lovingly at each other and holding
hands.

The waitress, taking another order at a table a few steps away,
suddenly noticed the woman slowly sliding down her chair, under the
table and under the table cloth but the man stared straight ahead.

The waitress watched as the woman slid all the way down her chair
and totally out of sight under the tablecloth. Still, the man stared
straight ahead.

The waitress, thinking this behavior a bit risqué and worried that it
might offend other diners, went over to the table and, tactfully,
began by saying to the man: "Pardon me sir, but I think your wife just
slid under the table."

The man calmly looked up at her and said: "No, she didn't... she
just walked in.
