Hot Summer Job/Clean her room
You really should do something nice for her. It seems like you tease her more than anything else. Besides, you can spare a few minutes to tidy up. If nothing else you'll score some sibling points by getting mom off of her back.
But as you try to sift through the mess it quickly becomes apparent that there's more going on here than one man can handle. Is this art trash? Is this trash art? You find a t-shirt wrapped around a pair of scissors. Unraveling it you find all sorts of strips and 'patterns' cut out of the shirt. Is this also art? Or a stress relief thing?
You try to focus on the obvious things. Random dishes. Dirty clothing. But you keep coming across weird stuff. Like an electric toothbrush. Why does she have that in her room? And training bras? Only a few, but still. She is still totally flat, isn't she? Not that you've been looking...
You do what you can and manage to make a noticeable improvement. But some of this stuff seems better left alone.
Is that all you're going to do?
