The Phlebotomist's F You T-Shirt

I know the world has gotten more casual,  
but a middle-aged stern-faced phlebotomist in a t-shirt?  
This surprises me.  
And not just any t-shirt.  
This one is that dull brownish red color  
sometimes referred to as oxblood  
It features big, deep, gothic dripping letters  
clearly spelling out the words  
Fuck You   
 
Her demeanor  
matches the shirt  
Her only words to me: Make a fist  
And so I do..  
 
Then she stabs me  
 
Nothing  
 
She stabs me again  
 
Nothing  
 
"Are you making a tight fist? she demands  
 
Yes! I am! Really! Very tight fist. Fisty Mcfist pants!  
 
Stab  
 
Jab  
 
No luck  
 
She ties the tourniquet on my other arm,  
goes closer to my wrist this time  
 
Victory.  
 
Twenty minutes later,  
taped on cotton ball removed  
a dark purple flower of death appears.  
 
Perhaps she'll stand by my grave  
in her oxblood t-shirt  
laughing manically  
 
happier than she's been in years
