Hmmm, on the one hand, we have
A - Jail time, Pedo charges (the police don't know she's older), fired from teaching FOREVER.
OR
B - Just tear your fingers free. Yeah, It'll hurt a little, and you lose some fingerprints for a couple weeks (I do this shit all the time working on acrylics) but you won't die.
Yup, option A makes way more sense, go for it!
