Balance

[ZonaIncerta]

Which weighs more, 
Aa hundred pounds of brick, 
Oor of feathers? 
Months of daily struggle, 
or a few weeks of contentment, 
stolen? 
Which tastes sweeter, 
water that was never gone, 
or the memory of thirst quenched? 
Balance
is not always symmetry. 
Feathers take so much space 
to weigh anything at all, 
Wwhile just one brick can 
tip the scales.                                            I like how you can use this both literally and figuratively
Something little small, and hard,               Using "small" here instead of "little" feels a bit more natural to me (and it alliterates with "something", which is a bonus) 
will never be something big and soft, 
even when the scales are in perfect 
balance. 

Enjoyed the read.
So, to answer your curiosity as to what people get out of your poem: for me it sounds as if it's saying "things can share a property, but that doesn't mean they're comparable, though unfortunately people use things sharing a property as an argument for them being exactly the same or having the same purpose".
Additionally, I have to admit I laughed a bit after reading the first three lines, because of the joke "a hundred punds of feathers weighs more because you also have to carry the weight of your conscience for plucking all those poor birds".
