Hello halo, goodbye glands

Hello to my halo,
Goodbye to my glands,
You can move a mountain with a book of plans.
You can't break a heart with my birthday wish.
You can't make a wave in a petri dish.

Tell them,
We think they're starving.
Tell them,
We think they're deaf.
Tell them,
We've seen them carving curse words into their desks.
Tell them,
That i'm a liquid.
Tell them,
It's been a gas.
Tell them,
They're frozen solid just behind the looking glass.

The mirror just flat,
The mirror's just glass,
Into the mirror let's try not to pass.
