glass may shed those tears for ice
glass wouldn't withstand high temperature
glass is afraid of fire, but
glass may drip your blood, and
glass may stick your blood stain with them, and
glass will leave some little part of them in you, butwhat you'll feel is only pain,
and you can't even point the little part out
they just stay in you
metal may be strong and hard
metal may seems cool and poor
metal may help you when you caught in trouble, but
metal may make you tumbling hard down to hell, when you caught in trouble
metal may seems undefeatable and never been understandable, but
metal may melted to everything that's extreme
metal may look fine outside, but
metal may cry out rusts secretly inside, and
nobody will get to know about, until the rusts creep outside
and that's the time it broke down, and
collapse.
glass or metal ( or human, after someone's suggestion and i think i missed it out xp )
you will choose to be?
they are pretty pity ( including the human, too )
after all
