No, don’t get out your gloves or head to the gym to work against a heavy bag. (Unless that’s your normal exercise routine.) But this is the appropriate time to give a gratuity (Christmas box) to those in service jobs – delivery, housekeeping, home care.
The association of gifts with Christmas goes back long before the origin of Boxing Day. And don’t worry about being a day late. The Magi brought gifts to the Christ Child — but they didn’t arrive the night he was born.
