When we went dancing the other night at a local Elks club, the cars in the parking lot told us the place was packed.
Sure enough, we couldn't get a table. Every chair in the place seemed to be taken. An acquaintance saw us roaming around looking for a place to sit and pointed out a table with empty seats.
The couple sitting at the table was friendly and told us to join them. Soon, the woman told me why they were sitting alone while their friends and relatives were jammed together at other tables: they were being ostracized.
