Michael: You have no space.
Jade: If I move a few things…
Michael: You should do like I do, I’m going to buy something new, I throw out something first.
Jade: Can’t do that. Old things might come in useful.
Michael: You’re impossible. You mean, you’re too attached to the old stuff to throw them away?
Michael: You’ve got this addiction to things. You buy something, you like it, you can’t throw it away. You shop. You hoard. Your house is full of clutter.
Jade: At least it’s organized. All in boxes.
Michael: You buy new boxes every month.
Jade: Not my fault. Chimps hoard. Everyone hoards. It’s a survival instinct.
Michael: What good is that when you live in a small condo?
Michael is very assertive, perhaps he is frustrated at having to lug heavy boxes around. Hence his exhortation, “You should do like I do,” his exasperation, “You’re impossible,” his quasi-analysis, “You’ve got this addiction,” and his weak-kneed conclusion, “What good is that…?”
Since Jade doesn’t fight back, we can only assume that Michael keeps his hoarding confined behind cupboard doors, and is thus quite human, or he is an obsessive-compulsive thrower-outer, and thus not properly human.
