It was a large mirror above the sinks, so she could see herself from the waist up. To see her skirt or pants, she had to stand on the toilet.
I don't know why she didn't buy a mirror for her bedroom door. The toilet mirror viewing stopped after maintenance complained.
Thanks to you and Mel the Redcap and PastryGoddess for explaining. I couldn't figure out what she was doing! But that makes perfect sense now.
I could - I just couldn't figure out how she was standing on the toilet SAFELY in the dorm!
Some of those are wall hung instead of sitting on the floor - so standing on them is more weight being supported than just someone sitting on them (some weight would be on the person's feet). Which might not be safe...depending on the person...and how long the toilet had been there - corrosion on the bolts that was hidden behind the walls is still going to weaken the support for the toilet.
I have never had a toilet break when I sat on it - the very idea sounds painful, though. And standing on it would give you that much further to fall on what is usually a solid floor (maybe not in homes - but hotels, dorm rooms, stores, and other business locations).
