Not only is Santa’s sleigh powered by transportation biofuel, but as reindeer eat lichen, which is half algae, it’s an especially advanced type. A green operation, more so since he has stopped distributing coal to bad kids.

It’s OK to leave a fire burning out in the fireplace when you go to bed.  Santa can easily handle this, for reasons too complicated to explain to grownups.

Rudolph recharges with a plain micro-USB, not one of those tiny Apple things. Leave a cable long enough to go up the chimney.  This is especially important given tonight’s weather on the east coast.

And most important, speaking of navigation: all electronic devices (other than musical instruments) confuse Santa’s GPS.  Leave them off, and spend the evening talking to each other, singing, cooking, and like that.
