Bird (Z) brought a Bird (X) back to the flock,
Bird (Z) flew with the Bird (X) and another Bird (Y) with some other birds,
Bird (X) met Bird (Y),
Bird (X) and Bird (Y) started hanging out.
Bird (Z) got thrown aside.
When Bird (X) and (Y) are together,
Bird (Z) gets left alone.
But somehow, Bird (Z) remembers that without it,
Bird (X) and Bird (Y) wont be that close at all.
Bird (X) and (Y) are always flying out together,
with other birds from their flock.
Bird (Z) feels outcast,
and shall just wish Bird (X) and (Y) all the best.
cuz Bird (Z) is Exothermic!
Bird (Z) forms bonds and,
Bird (Z) raises the temperature around it. :)
Bird (Z) shall be happy..
