BosGuy brain teaser

riddle, exercise for your brainEach Friday morning I post a riddle to get you to think outside the box and exercise your brain. If you are stumped, share it with a friend or colleague and see if you can figure out the answer together.

I’ll confirm answers in the afternoon so don’t worry if you don’t see your comment posted right away. I want to give everyone a chance to guess.

This week’s brain teaser:  What is black when you buy it, red when you use it, and gray when you throw it away?
