We call it New Year's Eve, but the ringing in of the new year in Scotland is called Hogmanay. As in other places, it is a time to start anew, with a clean slate and good luck superstitions. Also, as in other places, it is a time for hard partying. The rich traditions of Hogmanay are still practiced, although they've been given a modern twist.
In years past the house was thoroughly cleaned and the ashes of the last fire of the old year were swept out. This custom is still observed by many women while the menfolk make the traditional "trip to the shops" to stock up on peanuts. This involves several hours in the pub, eulogising Denis Law. ("Like Anna Pavlova so he wiz.") They return home around 9pm, eschewing the pavement in favour of a zig-zag formation across the neighbour's lawn, ending up in the fuchsias. They do not buy peanuts.
