Um, you can get shoes at Goodwill
Today I learned that my student who carries a Justin Bieber notebook does not do so in earnest. I am relieved.
I learned that the library rule about not putting your bare feet on the table did not make it into the Harvard orientation packet.
And today I learned that every time you want to say “um”, you should replace it with a breath. You will sound smarter. If you say “um” as much as I do, you may also pass out, but nobody ever said you should be conscious for grad school.
Here's what I'm learning in grad school 
Justin Bieber as a cultural phenomenon is a bit weird, but there are some good pop songs at the core of it, so I’m willing to forgive a lot.
This kid actually said that he carries the notebook “mostly” ironically. Mostly because he “sort of respects his pop decisions”. Or something like that. I did not press the issue.
