Seriously, you need them you absolutely do! You NEEEED them.
OK, OK. I know. You need food, you need shelter. Not jewelry. Or do you? Jewelry is just "pretty." Or is it? The oldest know jewelry was discovered in 2013 and dates back roughly 130,000 years (those crazy Neanderthals!) Humans have felt the need for "pretty" almost as long as they've been around. Therefore, I submit that art (and "pretty") is a need!
P.S. If you're in the mood to fulfill you're need for pretty, my on-line store is available to you at any time!
P.P.S. Of course there is a sales pitch, because I too NEED to eat!
