Ivory what?

ivory tower
noun
1. A hypothetical place where the unpleasant realities of life can be ignored.

2. To exist in a secluded world, ignoring everyday reality.

3. A really tall structure made of the stuff from elephant’s tusks and mahjong tiles. Oh, and old piano keys, too.

ivory hut
noun
1. Same thing as an ivory tower, but lower to the ground. Smaller. With no elevators. So you can’t get all high and mighty on yourself.

2. In my world, there’s a piano in there too.

Then there’s the treehouse. Which is just another hut, pretending to be a tower. I promise not to morph into one.
