I come from a large family and it was not unusual to have one or two more drop by just about dinner time.  Mom would always tell them to pull up a chair and eat with us.  They never refused.  When I built and furnished my new home I wanted to make sure there was always an "extra chair" .  By day these two chairs  sit angled with a small table between them  and they look beautiful.  But I love them pulled up to the table with hungry relatives, ready to fill their plates.
