HM- Tough to Remove

Carly Beth tugged at the bottom of the mask, trying to lift it off. It felt hot and sticky. She was panting noisily.
  She tried pulling the bottom with both hands. The mask didn’t budge.
  She raised her hands to the pointed ears and tried lifting it off. She tugged. Tugged harder.
  She tried pulling the mask off by the top of the head. It didn’t move.
  “Hey—it won’t come off!” she cried. “The mask—it won’t come off!”
...
  “I’m not kidding around,” Carly Beth insisted in her harsh, raspy voice. “I really can’t—get—this—off!”
  “Take it off! You’re not funny!” her brother shouted.
  With great effort, Carly Beth managed to slip her fingers under the neck of the mask. Then, she pulled it away from her skin and lifted it off her head.
