Spine

What does Becca have in common with a sea cucumber, a jellyfish, and all insect species?

Biology students hopefully got this one...

She has no SPINE!

Friend suggests activity that Becca knows she will not enjoy.
Does Becca say "no thanks, I'm not interested"?
No, Becca says sure, agrees to go, drive everyone, and takes to crying inwardly.

There is a reason she does this, and Dr. Anjelica Milanovich is primarily responsible.
Knowing the reason doesn't make it any better.
