THINGS EVERYONE ASSUMES I KNOW

so I had to look them up secretly
  1. Most internet slang, the first few times I encounter it.
    TFW?
  2. The song Stairway to Heaven.
    Yes. I finally caved and listened to it a few weeks ago. Literally had never heard it before.
  3. What famous actors look like.
    Like, I know Tom Cruise is famous but I can't visualize his face on command
  4. Anything about Star Wars.
    I finally watched them a few months ago. Then I looked up the Wikipedia summaries so I knew what happened.
