"T"
IS FOR TWELFTH NIGHT, TURKEY, TINSEL, TOBOGGANS
It is widely considered that all decorations should be taken down by the Twelfth Night to avoid bad luck. This superstition is based on a belief upheld until the nineteenth century, when decorations remained until Candlemas on 2 February, (40 days after Christmas). As the decorations were foiliage, people believed that the greenery contained tree spirits which had to be released to ensure spring would return and vegetation grow.
