Jack Frost is a busy elder spirit, and doesn't have time to nip at everyone's nose. The task of haranguing people in cold climates on a day-to-day basis is left to winter fey called Shiverjacks. These diminutive sprites invisibly colour the cheeks and prick the ear and nose tips of those moving about outdoors, but are also known to enter houses through drafty windows or poorly sealed basements. Once inside, they tug blankets askew, make off with hats and socks, lower the thermostat, and send chilly drafts across the floor. Once indoors, the only way to force them back out is to make a hot drink or have a hot bath or shower (they can't stand being around hot water). To really put them in their place, putting on a favourite show or movie and getting cozy under a blanket sends them into a fit of impotent rage, at which point their temper will melt them into little more than a puff of steam. This doesn't hurt them (besides their pride maybe, but that could stand it) and they zip back out of the draft they entered in to sulk in a snowbank or under an eavestrough, until they find another unsuspecting victim to pester.
