Curiosity is the very basis of education and if you tell me that curiosity killed the cat, I say only the cat died nobly.
Just like Bilbo I am feeling I am getting thinner and somewhat watery, only I don't have the ring... The ring... to me, it implied a bizarre mixture of unlimited super power and personal responsibility - the onerous burden that would eventually sap the bearer of their life.... Pure fiction, was it not?
I might need some rest - a good sleep and a bit more fresh air... hard to believe that could help... could be...
Interestingly, it happened right after the life-changing decision had been made... Not that I mind it, simply curious to know if there's still time....
Getting thinner and lighter in a way... Is it how they become enlightened?...Feels tingly, dizzy, wobbly - pretty much funny in a word... kinda disappearing...
upd.
Interestingly, 'thinner' in this case was used to imply smth opposite to 'thicker'... I don't know why it never occurred to me that it could be the opposite of 'fatter' (hm & hehe)
Other possibilities to consider:
fade away - only after the ultimate end
, in the Progressive aspect might imply the process of dying out as such;
waste away - only as the opposite to 'put on some weight' and 'become stronger', usually due to some illness;
peter out - mostly about an activity or a path/road;
fizzle out - pretty much the same as 'and then there was none' or simply 'nothing was left' and 'end in tears';
end up - when 'the end' is not a borderline between life and non-existence, usually with quite a negative connotation.
ps. So far so good
will wait till the next update to see how it goes
