I'm like a glass of water.

If you hit me, I might shatter
If you scream at me, I might crack
If you use me, I'll be drained of my life, the water, little by little
If you knock me down, every drip of life will fall out of me.
Drip by drip
Tear by tear

So please treat me right
Because you have no clue
How fragile I can be
