Long before, i knew Boxing day only as a day after Christmas (which is 26 December) where English Premier League teams should play a match. After extending my reading hobby to browser around wikipedia, it turns out to be the day (in commonwealth countries) when you open your Christmas present/gifts.
Since I’m a moslem, i think i will still use boxing day term as the time to watch my EPL team playing and perhaps opening my birthday gifts :P
Oh, thank you so much, guys :)
I’ll take the dark chocolate, you can have the other two \^_^/
