Weird note from Hari - help!

So I found Hari's room in Hurlbut, but it didn't look like anyone had moved in yet. I tried to find out if he had a roommate, and someone told me that his room was in a block of rooms called "psycho singles". !!! He's a bit odd, but he's no psycho!

There was clearly no one there, but I saw a corner of a piece of paper sticking out from under the door, so I fished around with my key and pulled out... a note from Hari!

Anna,
I knew you'd try to track me down! Nice work! I'm sorry we haven't hung out yet, but I'm super busy! Meanwhile, check out these awesome books I've found in Widener - it's just like in our old letters!
xo,
Hari

This must mean something. Hari has never used an exclamation point in his life. Any ideas??
