Student or Learner
Two days later, he left for Yorkshire and I prepared for what I’d come to think of as my “field trip” with Archer. Calling it that seemed safer and more businesslike than “meeting” or, God forbid, “assignation.” Still, I spent most of the day in my room by myself because I was afraid Jenna or Cal would be able to tell something was up with me. I was so nervous that I was shooting off tiny flashes of magic like a sparkler.
What's up? A common greeting.
What is UP with you? What is wrong with you? Why are you acting so weird.
Something is up with him. He's acting weird and I don't know why.
I can tell something is up with you. You are behaving oddly and something is on your mind.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
