She imagined, now, what it would be like to accept herself completely. Every mistake she had ever made. Every mark on her body.Every dream she hadn't reached or pain she had felt. Every lust or longing she had surpressed.
She imagined accepting it all. The way she acepted nature. The way she accepted a glacier or a puffin or the breach of a whale.
She imagined seeing herself as just another brillant freak of nature. just another sentient animal, trying their best.
And in doing so, she imagined what it was like to be free.
(The Midnigt Library by Matt Haig, episode Expectation)

Breaching​

A breach is when a whale propels its body out of the water. If more than half the body appears, it is considered a full breach. If half or less of the body appears, it is a half breach. The whale may spin in either a clockwise or counterclockwise direction, or the whale may choose to do a non-spinning breach, where it lands on its back or side. A chin-slap breach involves a vertical movement with a landing on the throat/belly. A whale may also propel the lower part of its body and tail out of the water in a tail breach.
