What a small world. I was going to say the same thing, exactly, or pretty close, with, maybe, a change to the sentences and the words.
I see kits all over for around three hundred. Add a little plywood, hardwood and finish materials and it should be around six, if you are going through a wood outlet. Of course, you can add a couple hundred or a thousand for a mattress.
“Maybe they built it out of some exotic hardwood that was milled by enchanted mice. . . . maybe they included the matress made of unicorn down?”
