Numbness in my arm

Me: ...
Nurse: Whats your name? *checking my particulars*
Me: Low... Jason Low.
Nurse: OK. *Tightens pressure on my right arm*
Me: ...
Nurse: *Takes out anesthetics needle* Do you need anesthetics?
Me: ... No?
Nurse: *Puts back anesthetics needle*
Me: (Gulp)
Nurse: *Takes out protective covering from the tip of the blood bag, revealing the thick needle*
Me: (Can I change my mind about the Aaarggghh.....)
Nurse: *Stabs me in the arm*
Me: (Hmm. That feels different...)
Nurse: *Looks at the bag and walks away*
Me: (Guess I don't need anesthetics after all.)
