The Scottish army play games in the dark: “officers waited on the men at special dinners ( haggis no doubt) while at the bells, the Old Year is piped out of barrack gates. The sentry then challenges the new escort outside the gates: ‘Who goes there?’ The answer is ‘The New Year, all’s well”
Highlanders burn twigs and bless dead animal with magic water: “in the Highlands…householders drink and then sprinkle ‘magic water’ from ‘a dead and living ford…After the sprinkling of the water in every room, on the beds and all the inhabitants, the house is sealed up tight and branches of juniper are set on fire and carried throughout the house and byre. The juniper smoke is allowed to thoroughly fumigate the buildings until it causes sneezing and coughing among the inhabitants…woman of the house then administers ‘a restorative’ from the whisky bottle”
At some point they sing Auld Lang Syne.
In short, pretend you’re a viking, break into your neighbors home bring them groceries, burn lots of stuff, feed kids fruit cake, dance while pigging out hence HOGmanay,play in the dark with soldiers and finally practice witchcraft.
See folks, it’s easy to understand other cultures if one puts a little effort.
