We’re on a long bus trip. My friend wakes up.

Friend: What’s that?
Me: Shh!!!
Friend: …
Me: … Oh. Sorry. Hey, how are you?
Friend: Sleepy. *grabs my phone to see a half finished sudoku* Huh? I thought you were gonna die. It’s just soduku!
Me: Sorry, was just in a train of thought.
Friend: What thought?
Me: See this square here, it can only be 2 or 5. So I thought 2 and seeing how that worked out.
Friend: So just.. guessing? I thought you were pro. You need a nap.
Me: I’m using Nishio Forcing Chains.
Friend: Huh. OK, you’re wide awake then.
