this is the good bit about living alone - pick and choose the bits of celebrating you want. For me that means one, maybe two non-light non-noise non-sparkly decorations on the desk, some extra snacks and drinks in case people come round, cards for my friends, small presents for my family, and I go to my parents for feeding in the evening. And I get plenty of mates coming round for a quiet cuppa because they can't cope with the tinsel, music and aging relatives at their family homes any more...
