Poem-A-Day: Day 6

Today's Prompt: For today's poem, I want you to write a poem about something missing. It can be about an actual physical object or something you just can't put your finger on (like "love" or "the spirit of Christmas" or something).

Here's mine, which I forgot to title when I posted it, but my working title is:

Abstract Amber Alert

I used to want to save the world,
I used to be so sure
I always could tell right from wrong
And evil versus pure

And then when I had children
I found the lines had blurred
What seemed so right at twenty
Now seems quite absurd

I want to teach them tolerance
Of everyone around
While teaching them all how to live
a lifestyle safe and sound

Is there a way for me to walk
along so thin a line
And end up with that confidence
That for now is not mine?
