Hi Larry,
Boxing Day is astrange name for a holiday. I think it's origins stems from charity purposes ie the Boxing of gifts to give to the less fortunate. Was done on the day after xmas. Nowadays I doubt anyone really knows why it's a celebrated holiday.

Fortunately the term Boxing Day doesn't come from

"Get In The Return Line At The Mall"

though I betcha there'd be a few potential punch ups in those long, long , queues
(haahaa)
best wishes
