I always wanted one and I didn't know why or how it would be useful so I didn't get one. But now I have one and it's just fun to like, cut a single cucumber without having to lug this big thing around and then have to wash something so unwieldy. Sometimes you just have to go with your gut!
Put on the robe, turn on adult swim or whatever, crank the ac, eat a late night snack in one bed and sleep in the other. The freedom of impersonal liminal space.
