I'll send you a series of care packages.
The first 5 will be full of dirt, just dump these on the floor.
The next3 will have moss and fungus, and a staple gun. Use it to attach them to the walls and ceiling.
The 9th box will be full of rocks. Put them in a pile, and use them as either a table or chair.
I'll also send you a $20 home depot gift certificate, which you can use to buy the clearance interior plants. Right now they are $2.61 each for 7gal container plants.
The last box will contain a big club. This is really a pre-historic sex toy. Use appropriately.
