Relentless
by johannespunkt
“I’m really not the kind of person to run away,” you claim, tightening the laces of your new white runner’s shoes. “Like, if you know me, you know that is so not me.”
I do not know you.
“I never ever go away, and I always come back.” You unfurl your fins from your torso like a set of wings. It’s a short pier and a long way down. The sea attacks the cliffs with a relentless kind of romance, the kind that’s not problematic in works of fiction. You sigh. “But I have to do this.”
You disappear.

They always say they have to. Sometimes, they don’t have to, they just want to. :(
The semantic difference is very thin between ‘have to’ and ‘want to’. And when you try to ponder it, and you try to justify your every move, you petrify yourself. “I want to feel better” becomes an accusation, and how could you be so heartless. You would rather just leave.
(There is no right way to do it, is there?)
Maslow had something to say about the difference between wants and needs. (I think. A Level Psychology feels like a long time ago…)
Maslow was a hack with no scientific method. He made some educated guesses. :P
Not to say there aren’t differences between needs and wants, but when it comes to emotions, the scale is rickety.
In British Sign Language, the sign for ‘I want’ and the sign for ‘I need’ are the same. (Flat of hand towards body, jerks downwards and outwards. http://www.signbsl.com/sign/want)
Downwards and outwards would to me, who speaks no sign language, seem to be a rejection more than a desire or requirement. I like this counterintuitive sign. (Okay, after looking at the videos it just looks like decisiviness and knowing what you want/need. But someone should design a counterintuitive language used for spies or something.)
