This is me trying to study right now.
Someone was watching porn in the library. They just left the laptop open with the porn playing in the background. I started yelling “there’s porn in the library” and pointing at the laptop. Isaac and I waited to see if we could figure out whose laptop it was. I left a note suggesting that they close their laptops and not leave their porn playing AT THE LIBRARY. Hopefully it helps this person figure out social propriety.
