She's always ready to lend an ear
With hair so light
Too bad you she won't hear
The devil inside her

Easy Riddle for You Today

I drift forever with the current
Down these long canals they've made
Tame, yet wild, I run elusive
Multitasking to your aid.

Colder, sometimes, rougher, true
But though I might make living easy,
I'm good at killing people too.

I have a body and head, but I'm not alive.

That downward thrust.
Sparkling spears
That never rust.
