How Can We Desire Sorrow?

I walked a mile with Pleasure;
She chatted all the way;
But left me none the wiser
For all she had to say.

I walked a mile with Sorrow,
And ne'er a word said she;
But, oh! The things I learned from her,
When Sorrow walked with me.

- Robert Browning Hamilton


Lifted this from Have A Little Faith. Interesting poem, and so true at times. Mistakes and trials come our way, and I guess we're allowed to slip into temporary sorrow to save ourselves from eternal regret in the future. Its all part and parcel of learning.
