Sounding Like A Knee Jerk

(I am assembling an exercise bike in my house when my cellphone rings. As I reach over and grab it, I bang my knee hard on one of the pedal mounts. It hurts, but I still answer the phone to talk to my friend. I was trying to ignore the pain and speak normally, but my voice must have been betraying me.)

Me: “Hello.”

Friend: “Hi, I was wondering if you wouldn’t mind going out to dinner tonight instead of tomorrow.

Me: “That’s fine.”

Friend: “…You’re sure that’s okay.”

Me: “Yeah, it’s fine.”

Friend: “Because if you really can’t I can still go out tomorrow.”

Me: “No, no, it’s fine. The reason my voice sounds somewhat stressed out isn’t because I am annoyed with you for changing our dinner plans. Right when I picked up the phone, I slammed my knee on this jagged piece of metal and it hurts so badly.”

Friend: “Oh!” *laughing*
