Random Riddle: 12-23-2013

Goofy, bucked, green or gold
Young and charming, wise and old
Sly, cunning, empty some times
Mirthful, uplifting, within the lines

A fleeting glimpse or prolonged show
I’m sometimes sad, sometimes mean
Sometimes I’ll say more than you know
Or betray what you think you’ve seen

Now, if you know me, tell me so
You have me too, you know!
