Why Can’t You Just Be Nice, asks artist Trey Speegle in this playful work. Well, why can’t you? Let us know—in 10 words or fewer—for a chance to win a framed 14”x11” print! We’ll choose our favorite response from among the entries. The contest will close at 11:59 p.m. ET on December 19, so don’t delay.

For a chance to win, simply:

1. Tell us, in 10 words or fewer, why you (or someone else you have in mind) can’t just be nice (be witty, sweet, fascinating, curmudgeonly—we encourage you to be creative).

2. Submit your response(s) here or tweet them to us at 20x200 using the hashtag #BNice by 11:59 p.m. on 12/19

We’ll share the winning caption on Tumblr!
