person A: Last week I was not feeling well at all. I missed a couple days of work and was so tired by the time I went back in.
person B: Aw_comma_ that stinks. What was wrong? Were you sick?
person A: I had the flu. The day I went back to work_comma_ I was so tired that I forgot to change out of my pajamas before going in!
person B: Wow! That's insane! I'm sorry that you had that experience! Hopefully you didn't miss too many days of work.
