My "interpretation", which admittedly was influenced by a few beers...
Paint nite was a lot of fun. I went with a friend I play racquetball with and her husband...it was only the tiniest bit awkward that they were celebrating their anniversary. I felt a little like a 3rd wheel, but they didn't seem to mind. This particular event was sold out although there were a few people who didn't make it ~ evidenced by the few canvases and paper plates with paint that were taken away once we started. It was easy to follow the directions of the host, who had a great sense of humor and admonished us not to make derogatory comments about our own and others work, that it's supposed to be a fun night out. Two hours later, this is what I had. Perhaps I shouldn't have had the beer, ha ha.
After we were done, we walked around the tables to see the results. Some people added dragons and UFO's....I would say these were folks that didn't intend for paint nite to be anything other than a fun night out. Others were a little more serious. If you decide to go to one of these events, invite as many people to go as you can. The more the merrier!
Some of the best results were from people that don't have any "artistic" abilities! Again, it was a lot of fun ~ I highly recommend you try one just for the experience.
