Yes, we give housewarming gifts. These days, unless the couple really don't have anything, it's likely to be a bottle of wine or some flowers for the 'lady of the house'.

Marauder times ... Not so much the wine (unless it's a housewarming party) but maybe a revolting ornament, or a coffee table book (that's a stylish looking book that looks good but no-one ever reallly reads)
